I have an RCA wood table model from about 1932. It uses a 57, a 58, a 47, and a 80 tube.. Can anyone help me to tell what the model number is?

Looking through My RCA Radio Set Socket Layout book 1921-1935 I do not see an RCA with that layout. I did however see a 1932 Belmont 41A that has that tube layout.
No schematic for it here on NA though...
Radio Museum shows it as a Cathedral http://www.radiomuseum.org/r/belmont_41a.html

How sure are you of that tube lineup? I'm thinking that there should also be a type 55 tube, to serve as demod/AVC/first audio amp.

Also, are you certain that this is an RCA-branded set? In the early 30's RCA made sets for other brands, such as General Electric.
