You have failed to mention that your puzzle picture shows an extremely rare Hotchkiss Grégoire Grand Sports 2-door body by Paul Charon. Only 247 Hotchkiss Grégoire's were built, of which 235 had been 4-door sedans, a couple of Convertibles, which leaves 10 or less Grand Sports! The failure of these cars to sell in large volumes, must in part be due to the fact that they retailed for more than twice the price of a similarly sized six-cylinder Citroën Traction 15CV!
