Only high end Philcos of 1937-38 had decals around the various knobs indicating their function. Beginning in the 1939 season, this practice of applying decals around the various knobs was extended to all but the cheapest models...and even some of the cheaper models have something above the band switch knob, if there is one.

I'll add to what Ron has said. Philco (and others) usually included a User Instruction sheet describing antenna and ground hookups, how to tune stations and day/night reception issues and almost always included a diagram of the radio front describing the knobs and fuctions.

These are ultra-rare today and were the next thing a new owner would loose or throw away after the packing crate/box. I have been lucky to rescue and preserve a very few of these in my archives.
