Well, I've eliminated Chapron, Saoutchik, Figoni et Falaschi. I've found a zillion references to their 235s that this car doesn't look like.
I can't identify anyone else as having definitely been associated with Delahaye that late in the game. But some "maybe"s I've found are:
Guillore
Carrozzeria Rocco Motto
Pennock
Vanden Plas
Is it any of those??
You are.Can't you read, Arunas?
The point is yours. Now, if you can ID the coachbuilder, I'll give you a second point.
You have 24 hours.
1951 Delahaye 235 Faget-Varnet.
