Congratulations, pguillem. Don't worry, you deserve the point as you were the first to supply the complete answer. The question whether it was a Skoda from the thirties was surely helpful, but as I didn't consider it precise enough for granting a lock, it was open to everyone. I understand your Google Image Search as the classic one where you put in "Skoda 860" and get 470.000 pictures to choose from. Nothing wrong in using that, we all do that I guess. You are right, this Skoda 860 Cabriolet de Ville from 1930 was bodied by the coachbuilder J.O.Jech from Prague.
