Original Vintage 1924 Atwater Kent Model 10C 4700 Radio For Restoration
Based of the information I could find I think this is an improved version of the original Model 10 “breadboard AM radio. The changes from the earlier version include eliminating the potentiometer that controlled RF amplifier grid bias and replacing it with an 800 Ohm damper resistor, and eliminating the bypass capacitors on the RF amplifier filaments.
The set uses two 201A tubes for the Radio Frequency section, a 200 tube for the Detector, and two 201A tubes for the Audio Amplifier. It could use a 200A tube with a thoriated tungsten filament for the Detector and reduce the total filament current by 0.75A. This breadboard has mounting holes in the four corners. I have been told that it was likely built to be mounted inside of a cabinet made by Pooley Company in Philadelphia, PA. On this breadboard the power cord is attached to the bottom. This is another clue that this breadboard was intended to be mounted in a cabinet.
