It was actually duing production of the 1937 models that Philco switched from cloth to rubber AC cords. I've found some 1937 Philcos with cloth-covered AC cords which had every appearance of having been installed at the factory.

"Waste not, want not" was the catchphrase of the day...if Philco decided to switch to rubber AC cords, you can bet that they first used up their stock of cloth AC cord...
