Have you ever hard of the brand or manufacturer Criterion? A few days ago I bought a Criterion radio. It is a low-boy console with 7-tube TRF chassis. I already have it playing.
Sombody is on E-Bay now trying to sell a page from a 1930 Blish, Mize & Silliman Hardware Co. catalog showng Criterion radios. The two models shown on that page use screen grid tubes, so they are probably one model year newer than the radio I have. They may not even be from the same maker. However, the chassis in my radio is painted, and I see that a radio in that ad has a chassis finished in "gold moire," which would mean paint.
