Base car should be easy.
For one point, please respond and identify this car and its coachbuilder.
Alfa Romeo 6C 1750 GT with Stabilimenti Farina coachwork? I'm guessing from 1931.
The base car is an Alfa Romeo 6 C 1750 indeed. But the coachbuilder isn't Stabilimenti Farina.
How many guesses do I get? :P
Is it Castagna?
You can guess as often as you like, as long as it is one guess at a time and nobody else comes up faster with the answer. I won't lock it for you, because IMHO the base car was very obvious. The real puzzle lies within the coachbuilder. And it is not Castagna...
James Young?
No
Worblaufen?
No, but it is a Swiss body. ;)
That should make my guessing easier :P
Graber?
No
I don't recall ever seeing a body style other than a spider, but I'll take a guess anyway. Brichet?
Not that one either
Oh man...I'm running out of ideas here. Is it Heber Freres?
Sorry, no
Gangloff?
No
Tuscher?
No
Wow. I just ran out of Swiss coach builders without having to dig into books.
Was this car originally wearing its Swiss coach, or is it a later rebody?
I think it is the original body. The coachbuilder manufactured at least four different bodies on the 6C1750 chassis.
On a side note, this is a really beautiful car. Do you know if it's still in existence?
Next guess: Bernath Willy?
It is not by Willy Bernath.
I couldn't find anything on the web about the existence of the car.
Do you know if that is a real or faux cabriolet?
It is a real one.
I am stumped. What else besides Alfas did the coachbuilders provide bodies for?
They clothed car chassis from Germany, France, Belgium, Switzerland, USA and Italy (at least), truck chassis and buses.
Hartmann?
No
Lol...Surely it has to be Langenthal.
Sorry, not that one either
Ramseier?
No
Wenger?
No
Coachbuilder from Italian, German or French neighboring cantons?
Yes, partly
Hess?
Finally!
Congratulations, it is a convertible body by Carrosserie Hess. One point for you.
Wow. That was a learning experience. It is a beautiful car indeed. Do you have any other photos or information about the car?
Sorry, no. I took it from an article about Hess where there was no further information about the pictured cars.
