I've got another one. Pure luck, because this is TOUGH. I was searching for picture N°3, googling "Philco", and I found PICTURE N°1. It took me some time but here it is:
#1 is a 1931 Philco radio-timer, design attributed to Norman Bel Geddes, who just happened to drop by at Philco's for a short period (same as Alexis de Sakhnoffsky).
Bel Geddes, although a very important designer and visionary, had little to do with cars, excepts for a few concepts (see below) and the design of the Futurama pavilion for GM at the 1939 World Fair. He id said to have helped a bit for the design of the Chrysler Airflow, and to have designed, in 1946, a new grille for the postwar Nash. I suppose this means the 1949-50 bathtub model, because the 1946-48 grille was a carryover from 1942.
