Solved - MJW #545 - Citroen C4 "Vent Debout" by Pierre Delcourt 1930

[woodinsight]

Who can identify this unusual car?
The base car should be easy but who is the designer/coachbuilder and what was it called?
The year it made its debut is also required.

[Otto Puzzell]

Surely a forerunner of this car...

I think you may have posted the prototype of the puzzle car.

Experts?

Citroen C4 but who did this elegant and early form? No idea.

That's the correct identification of this unusual car.
Well done and another point for you.

And if you don't "vent the boot" (English translation), it will develop a musty odor.

Hello and sorry for my English.
Pierre Delcourt was my grandfather. This car has started being built in 1928. My grandfather worked in aviation during the First World War. And when he decided to build this car was the first to make wind tunnel tests. The body was made of paper mache (it's true) and contains major innovations, such as turning lights.
This car was burned in 1939 or 1940 so it does not fall into the hands of the Germans. She had more a hundred thousand miles on it.
Some of this information is in the book "Toutes les citroen" published by René BELLU.
I know that a french reconstructs a full size car and I would love to have of information. Thanks to post a message if you have news.

Hello and a warm welcome to AutoPuzzles.
Thank you for that extra information and I'm sure that information on the reconstructed car will no doubt come to light in the future.
