Console style radios became popular around 1932, and production went through WWII until around 1950.
Based on some books and photos I have, I would guess yours is into the '40's. Earlier models were a bit more ornate.
That chassis is in very nice condition. Definitely worth restoring. Do NOT plug it in. Not even with a variac. You must replace every capacitor in it before you turn it on, and at least check every resistor.

Post your picture and you'll have an ID in a flash. Tons of info and help on cabinet restoration as well.
Good luck!
