It seems to me that I remember that the ID of the mask had shrunk on one of mine. I had to gently, with sand paper, increase the ID to allow it to not grip the drum.
It is very common on these for the osc. coil on band 2 to have the Philco nitro cellulose disease. I had to rewind both osc. coils on my 37-116's. If you see green on the coil, rewind it! Most here who have worked on these have had problems with band 2 because of the coil. I know on one of mine, the coil originally measured ok, but by the time I got it reassembled, it was bad.
