Hi Pal:
Another hour with no result. The year is a bit out of my range anyway.
As I am as interested in seeing the puzzle solved as I am solving it myself, please unlock it. And..........if I am not mistaken, the term "Sedan Decouvrable" is what we are looking for and we need to hook that up with a Swiss coachbuilder.
As a BTW, I had forgotten that this was also a favourite French body style and my PC became clogged with images of Peugeots, Citroens and the like.
