Correct! Further on that;

"Colotti Trasmissioni". See the link below.
Specified for GTA and GTAm. With "dog clutch" ....

Sorted for me. Based on documents and experiences.
"The 1750 GTAm used/could use the 1600 GTA mechanical clutch in combination with a GTA or a T 118 Colotti gearbox."

Different sets of gear ratios were on offer by Autodelta. Special Gruppo 5 gearboxes on request.

As the "3. Options"-list in post #500 of this thread, and stated in "Alleggerita" 1st edition tells us that.

As is stated in FIA Form #1576 in such a way that it gives room for for different applications.

Plus what some Colotti documentation suggests and confirmed by the "Alleggerita" list.

Does Appendix J say anything about this? Opinions?

Ciao, Olaf 👌🍀

I learn a lot a the moment! Thanks all!

5 SPEED CONVERSION STRAIGHT GEAR WITH DOG CLUTCH GTA 1300/1600 = GTAm

When I went to collect 153 2307, in a trash can, was a complete Colotti box with about 3 sets of ratios and a bunch of other parts. So clearly had been used on the car, yet for a lot of the local drivers, not practical, as a 'difficult box' to use.

I learned driving a non synchro truck

Good morning fellow members,
I would like to share a few pictures that my good friend N.Lyras (aka nino1969 in AlfaBB) entrusted to me from his visit at the Alfa Romeo Museum last July, we are looking at Alfa Romeo 1750 GTAm tipo 105.51 telaio AR 1530782.
Thank you.

Dear fellow members, the following picture came up on facebook, it is from the Balocco test track, should be late '80s or early '90s, judging from the 164 in the back round. Can any of the fellow members identify the red GTAm?
Thank you.
Takis.

 

[Zagato_Olaf]

Wauw Takis,

Interesting picture!
Maybe someone remembers from what publication this was or what helmet livery this is.

Ciao, Olaf 👌🍀

Hello members,

I decided to add the second 1750 GTAm in the UK, that was built locally with Autodelta parts.
Status to be discussed. I don't know yet how to catagorize this car.

# Unknown number, mid '70s local conversion to GTAm
A 1750 GTV type, 105.45 (RHD). Registration VPK4G. A mid 1970's UK privately converted 1750 GTAm with Autodelta and other spare parts. Raced in the UK.
Was crashed at the end of the 1970's.

Quote by Adrian Bertorelli;
"Olaf Roeten, no sorry only the UK registration number was VPK4G it originally was a 1750 GTV white with a black wabesco (webasto? Olaf) roof
First owner was Alfa GB."

"I was 17 when my mother got this car and I learnt to drive in it
This was the car that made the whole family fall in love with Alfa’s."

Silverstone 1977.

I guess you have to catagorize it as 'mid 70s period build & competition history', which places it more authentic than say a '90s or 21st century build. However, it does suggest that it no longer exists, so all is hypothetical anyway.

 

[kengta]

Both the Bertorelli racers, the real GTAm and this one were written about in the AROC UK club magazine in era I believe. I have the articles. I never thought of the RHD as a GTAm no more than I thought of the 1969 GTV Bulova Racer that carried Autodelta parts in 1971 (no wide body) a GTAm.

But maybe if there were GTVs built into racers using Autodelta parts at independent shops in Italy and we call them GTAm then why not this RHD GTV built in the UK.

Ken:

I agree with you on this but with one condition: it would depend on what year it was built.
If built in 1974, it should be considered as a GT Am. If built in 1976, it should be considered a replica, since the “prime” years of GT Am racing were well over by then.

Does your AROC UK article mention what year it was built?

Jim

 

[kengta]

Here's one Photo of the Bertorelli GTV from the AROC UK magazine from sept 1972. Note it is being called a 1750 GTV. And so far that is all I find on this car.

[Zagato_Olaf]

Interesting, Ken!!
So we have 1972 and 1977 as dates for the same picture.

 

[vsharp]

I think this was the car with a purple-ish color scheme at some point. I've seen period color photos of it, maybe somewhere else in discussion of GTAms.

Maybe I miss labeled the photo. Doubt I can check but will try.
