It's true that the 135 was launched in the 30s, and it soldiered on into the 50s. However, Delahaye had no body building facilities and thus were dependent on coachbuilders. How the car looked (except for the grille) depended on whichever coachbuilder bodied it and since they were bodied as one offs or as part of extremely limited series and could iterate incorporating the latest styling trends quickly, unless the buyer wanted a more conservatively styled car. This body is designed in a style quite typical of french luxury cars of the early postwar period and looks fairly different to a prewar car. Ditto with "razor-edge" styling, which was much more of a postwar british trend, than prewar.
