Well, my Ghia references didn't turn up this exact photo . . . but seeing as this clay styling model has no greenhouse, I'll say it's the convertible Chrysler C-200 rather than the coupe K-310. Probably about 1952, in the Chrysler styling studio before the actual construction work was farmed out to Ghia in Italy. No idea who the modeler is.
All of that seems to fit the photo the best - but we all know what THAT means here on AutoPuzzles, so it's probably all wrong!
