Un bellissimo novembre

Car used for the film “Un bellissimo novembre” is one of two four lights version Alfa Romeo 33 Stradale cars, precisely the one with VIN 750.33.112 that is in Arese Museum today. This version is slightly different from the first prototype produced at Settimo Milanese Autodelta factory, and was completed in 1968 on lightened chassis, thought for racing.
Among the papers left as Autodelta’s heritage, there are some indicative letters written by Scaglione to Chiti, which could explain the 33 Stradale (with four lights) genesis. There is the formal accepting of onus to build the prototype at Autodelta premises based at factory’s involvement in providing all necessary materials, logistic and skill, as visible from the Scaglione’s act dated 17 December 1966, and Chiti’s affirmative answer dated 29 December 1966. Already, 2 February 1967 Scaglione confirmed (and paid) the wooden form used for body hammering, to Giovanni Raniero from Orbassano near Turin. On 16 March 1967, two complete body panel sets (320.000 Liras for “due lastrature ”in 12/10 aluminum and not Peraluman) were paid to Saracino & Lingua from Druento near Turin. (Saracino & Lingua has produced almost all body panels for Scaglione’s prototypes physically). The first four lights (a doppia parabola) prototype (still with “old” code 105.33.001 stamped on chassis) was assembled at Settimo Milanese almost entirely by bodywork specialists Carnovali (engaged for occasion) and Scussat (already Autodelta employee) from aluminum panels provided by Saracino & Lingua. During the works (4 August 1967) Chiti asked Scaglione to test different windshield wiper position (remember the different wiper position on those two cars), and to find solutions to reduce the weight for one of Stradales intended to participate at 24 hours of Le Mans in 1967, together with open “Fléron” version cars. All the chassis for Stradale, based on steel tubes were elaborated at Autodelta and not at Aeronautica Sicula, and were 10 cm longer wheelbase to obtain more comfortable ****pit. As the racing program showed serious delay, Le Mans race was excluded from the program, and Stradale in its lightened version remained unfinished until March 1968, when Scaglione finished his engagement with Autodelta and left Settimo Milanese and Alfa Romeo forever. Before definitive farewell, he gave final help in finishing 750.33.101 (the first “parabola singola”, twin lights, sold to H. Wessels in US) which was made in Peraluman, and left unfinished “competition” Stradale 750.33.112. That unfinished car was the second four lights version made from second aluminum set produced by Saracino & Lingua and is now in Arese Museum. Marazzi has produced 11 Stradale cars and nine of them have known history. Cars 750.33.110 and 750.33.118 left no traces in documents, though Zeccoli has remembered that he delivered personally to Reza Pahlavi one Stradale that could be one of this two numbers. Two cars with four front lights were not street legal as they have lights lower than minimum allowed and remained without registration (the car from “Un bellissimo novembre” had plates loaned for movie purposes) The story that Arese Museum car is later creation by Giordanengo, over racing chassis is pure urban legend. To create shorter Stradale body over racing chassis is impossible for numerous reasons, which is useless to explain here.
Here is 750.33.112

The car in the Museo Storico is authentic. It is not replica, it has nothing to do with replica and its VIN is 750.33.112. If you examine carefully its top, you will find answer to one of your statements. Its wheelbase is the one of Stradale version and is 10 cm longer than presumed racing chassis wheelbase used for replica. For more clearings, send letter to Mr. Lorenzo Ardizio from Museo Storico. Here is address.

I am not sure that I have received your message. However, before considering your observations, look for a moment these photos. Here are both versions from the same period. Take Style Auto review from 1970 where you can find rich material about 33 generally and both Stradales on the pages, long before any possible replica was contemplated. If you insist that the car in the movie was first version made at Settimo, well, it is possible because in those times both cars were Alfa’s propriety. You have noted that the film example has roof wiper and profiled “scudetto” with moustaches, but you have omitted indicative “detail”, which is the back of the car, completely different on two versions. The one in the movie has openings in the fenders and different grill for cooling than the first version. It is theoretically possible that whole rear part was borrowed from the second version, but it is not plausible. The question of rear view mirrors is irrelevant as they were easy to fix or remove. Which car is used for film is of no importance for me, I just wanted to point that there were two four light prototypes produced, and that the Museo Storico car is genuine. To me personally, the second version with its golden wheels, openings in fenders and long grill in the rear, is probably used for film, though nobody can exclude that the car used was the first prototype.

Hello members,

May I link you to Robert Little's website on 33 Stradales?
It might help in establishing what is what.

Ciao, Olaf

Autodelta Golden Years History Site

By the way, the link to Pahlavi showed me this text. Can't read the text though.

Alfa Romeo 33 Stradale | Stility.com
The text in Autodelta Golden Years is mine. The other text that you have pointed is in Serbian by someone that made important effort, wrote literary nice article but with numerous substantial errors. I have seen it (with another text also in Serbian in another site, equally well made and equally full of errors), few years ago, searching for abuse (spoofing is the word I think) of my name (and even some photos) in different blogs and forums. However, that is not the topic of this post. The fact is that TWO four light prototypes were produced from the panels delivered by Saracino & Lingua in 1967-68. The first one with roof wiper and with closed surface of fenders, destined for major shows was assembled at Settimo Milanese inside Autodelta factory, and other one initially intended for racing was finished (from aluminum pieces) at Marazzi in 1968. As the measurements at Balocco showed turbulences around the back fenders and field of increased pressure behind the wheel, Scaglione (obsessed with aerodynamic of the car) tried apertures to lower the pressure and increase fluidity. The other changes were numerous and frequent, sometimes not visible, but the car was built over “classic” Stradale chassis based on steel tubes and longer wheelbase. The first prototype is now in Abarth Collection in Osaka and the owner is Shiro Kossaka, and the second one, VIN 750.33.112 is in Alfa Museum at Arese. Few well-made replicas in Giovanni Giordanengo’s workshop are almost identical copies of original cars but with Montreal engine and more ****pit comfort. The photos published are from different 33 cars (both prototypes with four lights and various twin light cars), and there is no exclusive shots among them. Set of very nice 750.33.106 car photos were offered (inside the abandoned factory yard) to R. Paolini’s registry two or three years ago by (so declared) author for high price (not purchased).
On the photo below, you can measure the wheelbase of the Arese car. Take declared overall length of the Stradale from the first nose point to the last one on the tail and measure the wheelbase, and then convert obtained result with given values… The result is longer chassis.

The VIN of the first prototype produced is AR 105.33*01*. It is stamped on the chassis of the car in Abarth Collection, Osaka (see the photo). The other chassis is N° AR 750.33*112* and it is on the second prototype, now in Arese Museum (sorry, no photo of it). The photo (big one) you have posted is from Ruoteclassiche, Italian magazine, number from September 2016, dedicated to Franco Scaglione and his 33 Stradale, and it shows second prototype now in Arese Museum. The small photo beside, should be the car discussed few years ago in one Spanish forum and it was described as rear fender of one of Giordanengo’s replicas with reinforcement of the aperture. (I have never seen other photos of that car and so, I am not sure about that). In one serious discussion about four light prototypes and their respective VINs, in French forum Diva, one-renown expert (present also in this forum) asserted (as I have done too) the existence of two four light bodies made in 1967-68 (see the citation). In two recent photos, you can observe the rear of 105.33.01 Osaka prototype and 750.33.112 Arese car. Osaka car is the same as the one present in two period photos attached. The prototype 750.33.112 was tested for advanced aerodynamics and Scaglione proved various solutions based on apertures in the rear fenders, and behind front wheels. With its front section of 1.406 square meters, the measured coefficient of resistance was 0,40 Cr, good but not outstanding, and the turbulences were observed (measured with color bands-see the photo) behind wheel arches. There was also increased pressure observed inside wheel arches, and Scaglione judged that as fan effect of the wheel design. As a remedy he tried different apertures in the fenders and behind front wheels, and indeed, he lowered the penetration resistance to 0,37 Cr, and improved the fluidity. The increased pressure in the wheel arches decreased considerably also. That allowed one of Marazzi produced cars (750.33.104) to achieve standing kilometer in 24 sec and accelerate from 0-100 in 4.9-5.1 sec despite factory declared 5.5 as measured time. The car showed good handling and stability during test. Here you can see also the assembling of Giordanengo’s Stradale and final product. It is very nice clean and well-made car, but it is not 33 Stradale.

This discussion is going in senseless direction. To me is indifferent the point of view of anyone in this forum, and I defend ones right to have different opinion. However, to clear the point, the photo posted (small one) is not authentic Stradale (otherwise I require, I insist on proof) and beside it does not explain anything. For PSK, Stradale was raced in its basic form in more than one occasion. It was part of Scuderia SCAR Autostrada from Florence and driver was Spartaco Dini, than by P. Laureati and A. Fischaber (chassis 750.33.106 and 750.33.103) as privates and so on during seasons 1968, 1969 and 1970. For curious people, here is the interview from mid ’80 with Carlo Chiti and Teodoro Zeccoli about Stradale years at Settimo Milanese. It explains numerous inquiries. I have not time (nor necessary skillness) to translate it, so you can enjoy it only in Italian.

interview Chiti & Zeccoli

La 33 stradale raccontata da Chiti e Zeccoli.

Avevamo un'auto da corsa che vinceva e un motore otto cilindri a V che poteva essere facilmente adattato all'uso stradale: non potevamo lasciarci scappare l'occasione di creare una Gran Turismo derivata direttamente da una macchina da competizione, che desse immagine e spessore a tutta la gamma della Casa. E che avrebbe rappresentato, tra l'altro, la migliore risposta dell'Alfa Romeo alla Fiat Dino 2000, la coupé torinese nata l'anno precedente proprio per offrire il meglio dell’esperienza delle corse (il motore V6 Ferrari addomesticato per l'uso stradale) su una macchina di serie. Carlo Chiti guarda le fotografie in bianco e nero sparse sul piano della sua scrivania alla Motori Moderni, appena fuori Novara, e ripensa a quei ruggenti anni 60 passati all'Autodelta, alle porte di Milano. Ruggenti non solo per il boom economico o per la scoperta di un'inedita generazione attiva in politica, quella dei teenager, ma anche perché alla presidenza dell'Alfa Romeo c'era Giuseppe Luraghi («il miglior presidente che l’Alfa abbia mai avuto», confessa Chiti), un uomo che amava le sfide difficili.
In questo clima di rinnovamento e innovazione nacque la 33 Stradale, una vettura prevista in 50 esemplari e poi costruita in soli 18 pezzi. Un'impresa contraddittoria nell’anno che vide la luce della 1750, berlina costruita in 101.880 unità. Ma contraddittorio era anche Giuseppe Luraghi, uno spirito libero.
Circuito di Monza, settembre '67, Mostra delle vetture sportive: debutta con le luci della ribalta brianzola la sportiva dell'Autodelta che vola sospesa nell'aria dalle vittorie della 33/2, il prototipo che al debutto sulla salita del Fléron, con Teodoro Zeccoli alla guida, riporta lo scudetto delle Alfa da corsa sul primo gradino del podio, dopo 14 armi di astinenza dalle corse e dall'assolo della 6C 3000 CM. Tre uomini le fanno scudo: Giuseppe Luraghi; Carlo Chiti, direttore defl'Autodelta e padre spirituale del telaio e del motore della 33 corsa; Franco Scaglione, autore del disegno e della realizzazione della carrozzeria della 33 Stradale, conosciuta infatti anche come Coupé Scaglione, un uomo controcorrente.
Ma come nacque la 33 Stradale? Racconta ancora Chiti: «Luraghi scelse uno dei bozzetti che aveva disegnato Scaglione e mi disse: 'costruiamola". Facemmo tutto all'Autodelta, a Settimo Milanese. Il telaio e il motore erano, a parte qualche modifica, gli stessi della 33 da corsa; la carrozzeria dei primi due esemplari, in alluminio, venne modellata nello stesso reparto dove si montavano i motori per le competizioni, con Scaglione che dirigeva i battilastra prestati da Zagato su come si doveva modellare il nuovo materiale. La 33 Stradale nacque in pochi mesi, da gennaio a novembre era tutto finito, dagli incontri per definire le linee della vettura insieme a Scaglione, che avevo scelto perché era specializzato nel disegnare Gran Turismo da sogno, alle prove di Zeccoli a Balocco. Nel marzo di due anni dopo, nel '69, l'ultima 33 Stradale usciva dalla carrozzeria Marazzi di Saronno, che vesti gli autotelai dalla terza alla diciottesima vettura. Avrebbero dovuto essere 50 ...». Conferma tutto Teodoro Zeccoli, collaudatore principe dell'Autodelta e pilota dall’invidiabile palmares sulle Sport Alfa Romeo. «La 33 Stradale? Ebbe la Montreal come nemica, che le venne preferita perché il progetto della coupé sportiva a motore anteriore era costato troppi investimenti per rinunciarvi all’ultimo momento. E perché la querelle tra il Reparto Esperienze dell'Alfa e l'Autodelta non era ancora finita. Probabilmente, se non ci fosse stata questa disputa forse Luraghi sarebbe riuscito a far prevalere la 33 anche nei saloni della direzione oltreché su strada e su pista. Preferire la Montreal alla 33 Stradale fu uno degli errori più gravi dell'Alfa di quegli anni, una disfatta, perché la Montreal (presentata all'Esposizione universale canadese del'67 e prodotta solo a partire dal '71) era solo bella da vedersi ma in movimento era un disastro. Il telaio era completamente sbagliato: acceleravo e il muso si impennava, frenavo e strisciava per terra. E cambiare molle e barre di torsione non serviva a niente. Con la 33 Stradale invece era tutta un'altra cosa. Era la stessa vettura che correva, soltanto addolcita nel motore, nello sterzo meno diretto e nella tenuta di strada. Tanto che qualcuno, come la concessionaria Scar Autostrada di Firenze con Spartaco Dini, la usò anche in corsa. A Balocco raggiungevo i 260 orari e la guidavo con una facilità disarmante. Il motore poi aveva un'affidabilità invidiabile: le 24 Ore che abbiamo portato a termine sono lì a dimostrarlo. E per quanto riguardava le vendite non c'erano problemi, la 33 Stradale piaceva: lo Scià di Persia ne aveva una, come anche il conte Corrado Agusta, al quale la consegnai personalmente, e Susy Raganelli, la campionessa di kart». Per meccanica e aerodinamica la 33 Stradale era ai vertici delle due posti sportive. L'otto cilindri a V di 90°, con quattro alberi a camme in testa, montava per la versione stradale l'iniezione Spica invece che Lucas, particolari in alluminio invece che in magnesio, fasature delle camme ed a bassa alzata ed aveva perso una cinquantina di cavalli. La potenza specifica di 115 cavalli/litro, comunque, era la più alta tra i motori stradali: 700 kg di peso e 230 cavalli a 8.800 giri al minuto consentivano un’accelerazione da 0 a 100 orari in 4,9 secondi e una velocità massima dichiarata di 260 chilometri orai, vicina alla versione da competizione Fléron che registrava 274 orari. Merito, certo, anche della linea profilatissima, della coda lunga che favoriva la penetrazione nell'aria, come fin dall'inizio dimostrarono le prove con i fili di lana a Balocco. L'obiettivo iniziale era di costruire una vettura con il minimo compromesso per abitabilità e comfort e che avesse almeno il 95 per cento delle prestazioni dello spider da corsa. Il passo venne allungato di dieci centimetri, e i tubi centrali del telaio erano costruiti in acciaio saldato invece che in alluminio chiodato come sulla versione corsa. Il magnesio venne sostituito con l'alluminio: nei cerchi, più stretti, e nella scatola del cambio, a sei rapporti. Peraluman al posto della vetroresina per la carrozzeria, «perché era più bello a vedersi e perché anche le altre GT erano in lega d'alluminio», spiega Chiti. All'interno un abitacolo spartano, senza nemmeno lo Spazio per i bagagli, visto che il baule anteriore era occupato completamente dalla ruota di scorta. Alta solo 990 millimetri, la 33 Stradale impose a Scaglìone la soluzione delle porte incernierate diagonalmente, una raffinatezza forse inedita per risolvere il problema dell’accesso a bordo, complicato dai due longheroni principali che correvano nei sottoporta. Il prezzo di 10 milioni di lire su strada equivaleva a quello delle Aston Martin Volante e della Mercedes 600 Limo, mentre la Ferrari più costosa, la 365 Coupè, era sotto di due milioni.
 
Stradales & races

I know that purists will not appreciate this photo, but this are some changes in body design of 33 Stradale that Pietro Laureati did in Coppa Teodori 1969. This to prove the unfortunate presence of Stradales in races in those years…
P.S. Wheels are "wild", only to help the 33 to reach car carrier trailer

You find it all in here:

The Laureati Stradale is registered with ch.no. 106 for start no 438, Colle san Marco Hill Climb, Italy 24.8.69 though.

G.
Coppa Teodori is the name of Colle San Marco hill climb, the year and event are right, but not Laureati's name. He was baptized Pietro, not Piero. Just a mistake in the title.
 
Susanna Raganelli is beautiful woman of well-known Roman family, successful in hotel business and important Alfa Romeo dealers. She was world champion in karting in 1966 in KF1, and first Italian owner of one 33 Stradale, (chassis number AR 750.33.104), bought in 1968 (or early ’69), not used for racing, (ex Brigato, ex von Donhoff, ex Kiyoshi Takihana resold in EU to Clive Joy). Teo Zeccoli personally delivered the car (see photo). 750.33.106, though confirmed in Japan by some important and reliable sources, was always in EU (mainly Germany). The cars in Japan collections (Shiro Kosaka, Kiyoshi Takihama and Joshiuki Hajashi) were others (105.33.01, 750.33.104, 750.33.111, 750.33.133…) some resold in USA and EU. Laureati’s car was 750.33.106, not 750.33.105 (that is in Germany too). This list’s value remained approximate as collectors often resell those cars keeping anonymity. Above data are from Paolini Registry last updated in 2012.

Chassis 750.33.104 is the Pebble Beach and the Ville d’Este winner. To my knowledge has I nothing to do with Peter Kaus and Rosso Bianco museum
Everything is possible. (I am not interested in cars ownership particularly and I do not know it well). However, you should consider some details and data. From 1969 Auto Motor und Sport’s text and 2006 Pebble Beach show, passed 37 years (to Villa D’Este 2011 event, 42 years). Pietro Brigato was not simple car enthusiast, but owner of the important exclusive cars dealership “Old Cars S.r.L.” known for trading in “impossible” (like Ferrari F40, or Ferrari 288) usually unavailable models. He controlled the car from 1968 to 1984, when it was sold to Mr. Kiyoshi Takihama who resold it in Europe (probably wrong data) to Peter Kaus (he might be only moderator in trading) and immediately after to Count Hubertus von Donhoff (1988-89), who sold it again in Japan to Hayashi collection. The car was sold than in United States (owner’s name unknown) in 2004 and restored with new interior and changed steering wheel. Finally, the last known owner is from United Kingdom (Clive Joy) and the car was awarded in 2004 and 2011 at Pebble Beach and Villa D’Este car shows. There are nine known “Single light” Stradales. Just excluding all the cars that do not match the visible part of the tested Stradale, reduce list drastically. The car that Jantke has tested, was rare (if not only) completely black interior, with lateral indicators (Italian street legal version), and slide windows in Plexiglas. It is possible that the car was loaned to Auto Motor und Sport for testing, as Brigato did same testing borrowings even before to other important car revues. If you analyze carefully posted photos you will find out that excluding double colored interiors, opening windows, models without external lateral indicators, and moustaches on the front opening (also the only “single light” with roof wiper), it remains only 750.33.104 and may be another car with same configuration, but with no photos known. So, look at photos and judge by yourself.
P.S. My previous statement that 104 could be Susy Raganelli’s car is incorrect. I have seen photo of her car from good position, and it was version with opening windows system. (no VIN indicated)

Note that interior and board in both cars are identic (compare it to all other known versions). Note lateral indicators and same “scudetto”, and note sliding windows that are the same on both cars.

Here is a sample of pictures found on the net.
According to my knowledge, I would guess, from to top, that is vin/ chassis numbers.
Correct me Correct me if I am wrong
105.33.12
105.33.001---115.33.001
115.33.102
115.33.113/133
115.33.101
Your list is OK except the first part of the VIN for photos 3,4 and 5, that should start with 750, not 115...
 
ARGTAReg.
If you description of 104 in post 88, that the dark collard interior is an indication of 104. Is right
You also state the you have a picture of Susy Raganelli’scar.
Whey don you post that picture as a documentation of you statement.

Her is the picture of the Susy Raganelli’s car .
It’s the known picture.
Judged from the picture is the interior light and the door sides polster, does not have a horisontal profile.
Where what you post as the interior of 104 is dark and have a horisontal profile.
So I Has to repeat my statement you argue don’t hold water.

The ownership of the car in question
Ex Suzana Raganelli
Ex Giuseppe Lucchini
2014 Luigi Lucky Battistolli ???
And i think that Giovanni Palombo also have some connection to the car.
And it is a question if it was the car in the advert in Road & Track in 1971 by Fausto Annibaldi in Rome
I have noticed that you use mainly Diva as source of your observations. That is OK, as thanks to the experts (like Patrick Italiano for example) it is reliable source, but keep in mind that it is not the only valid authority on Stradale. Again, numerous (black & white) photos originated from our archive (they are free for use anyhow). Beppe Lucchini is usually connected to 750.33.102 from the period of Lecco plates (LE152482), and it was surely not Raganelli’s car. Not to repeat photos from Diva tread, just control the color of interior from 750.33.102 that is black and beige. On 750.33.104 interior is black (see the photo, again in Diva) and seats are competition version (10533.58.001.10, usually used on lightened versions), identic to the seats seen in test from Auto Motor und Sport. From the photo with Susy Raganelli in her 33, it is clear that it is variant with windows opening (look the handle) and from photos of the car loaned for testing at Tuscolo it is visible that the front opening is without “mustache” (different from 750.33.102) but with windows opening system (different from 750.33.104). The tested car is described as Raganelli’s propriety but there is no any VIN indication mentioned. Finally, Annibaldi was my neighbor in Rome and his car was kept in Raffaelo’s Garage in Via Giustino Fortunato. I do remember well that car but I have no idea about its VIN. It might be the same Raganelli’s Stradale, as the appearance was the same (car was without plates anyhow). It stood together with Ferrari P2 colored in gold and used for one Felini’s film. I will repeat that I am not expert for ownership of the cars so in that field I might be wrong easily.
Prototype N° 2 is in Alfa Museum at Arese, story about replica is invented.
P.S. Not only for 105, but also for 110 and 118 you could not find any data…
There was anything like “press” or demonstration car at Autodelta.
Chiti never send anything for testing from Autodelta. The tested cars were borrowed always from private owners.
33 Stradale documentation survived at Marazzi but without possibility of consulting.

75033.113 renumbered in 75033.133 (superstition reasons) ex Lord Cranworth collection (until 1982) now in Fratelli Auriana Racing collection, brought back to factory values and color. Here is the photo still with silenced exhaust system and bumpers for road going.
