The chassis is made of spot-welded galvanised steel, with the top and sides painted.
Very unusual: the volume control (reaction ?) for the 4th tuned circuit (Det.), and the slight reaction for the 1st RF by increasing the grid to plate capacity.

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.
