Please help clear up my misundersatndings about 6c2500s

[Ritmo100S]

I am under the impression that the 6c2500s were officially introduced as such at the Berlin Auto show in early 1938.

I also understand that prior to this time, some 6c2300Bs were enlarged (probably by Ferrari) in displacement to 2500ccs, and that the 3 carb, rather than the 2 carb intake manifold was installed..and that these engines might also have had different compression and cams than the 6c2300Bs. As far as I am aware, these cars and motors should be called T256s.

I have seen the 1940 Ala Spessas designated as T256s in some publications, but if they were not built until 1940 (or maybe 1939), why would they be called T256s and not 6c2500s, if the official 6c2500 introduction was in 1938?

I also understand that there might have been some technical differences between the pre-war 6c2500SS cars and motors and the T256 cars and motors, but have never seen any kind of clear explanation of exactly what that might have been.

Thanks for any input...

Why would he be asking such a question? We are all lost!!!!!

The 6C2500 was presented in 1939, not 1938, as for any source I know, see Fusi p381.

The "Ala spessa" and Spider siluro were also prepared for the 1939 Tobruk-Tripoli, earlier in the year than the presentation of the 6C2500 berlina. The first articles show indeed the Ala spessa.

The "prototype" of the 6C2500SS, or T256, both designation are used simultaneously in period publications, was indeed a modified 6C2300B MM.

Early 256/6C2500SSs show detail features identifying them as having been built on 6C2300B chassis.

You are correct. According to Anselmi it was 1939; not 1938 when the 6c2500 was shown at the Berlin show. The dates of the show were February 17th through March 5th, so the Ala Spessas must have actually been built in 1938.

Here is a link to a guidebook from that car show I just found on the internet! Stangely, no metion of Alfa Romeo.

Also, if the T256s were modified 6c2300Bs, shouldn't they have serial numbers beginning with 8 and not 9? All the cars in the list in Anselmi's 6c2500 book in the section T256/6c2500SS begin with 9...

What are your thoughts on the 6c2300B MMs that appeared at the auctions last year and this year, at Pebble Beach?

Both last years Oscar Davis black car (which sold for something like $2.5M), and this years unrestored red car (which the seller had for over 40 years and was bid up to over $1.5M and did not sell), have chassis and motor numbers beginning with 8, but have the 3 carburetor intake manifolds (the motor in this car is not the original, but the original motor was included, and it's S/N also starts with an 8). I have no idea of the internal configuration of the motors in either car, or in the original motor in the red car, which was included as a "spare".

I am checking with Mr.Callagaris of the 6c2500 register, to see what information he might have...

[gtv2000]

It has a 6C2300B chassis number, it is presented as a 6C2300B, it has a coachwork style tying with a 6C2300B, so what's the matter?

Have you never seen Giulietta Normales fitted with double Webers? Does it usually make them "Veloces"? I understand that some seller would like so, but nothing like that here.

The seller of this 6C2300B certainly won't cast a "made by Ferrari" history around it.

I certainly agree with you that the 3 carburetor intakes could have been added later, and that neither of these 2 cars maight have been originally built as T256s or pre-war 6c2500SSs, but do we know this for certain?

Is it possible that some "real" T256s or pre-war 6c2500SSs actually have serial numbers beginning with an 8? I think so...

Don't you think it is possible that some of the 106 (according to Fusi) 6c2300B MMs were not actually completed as 6c2300B MMs, and were renumbered with a S/N starting with a 9, and actually "became" 6c2500SSs or T256s??
