What I would do is to try and identify the chassis, or perhaps a near match. The chassis was probably made by a company like RCA, and you'll probably be able to date it by its tubes and layout. If you tell me what tubes are in it, I'll look through my schematics and see what I can find. It would also be helpful to have a photo of the chassis or a diagram of its layout.
