Hi all, I've acquired what I belive is a 1930s RCA Photophone MI-1213 amp see attached photos.
Yes she's a bit rough (apparently thats mainly dust not rust) and will need lots of work. But I'm trying to find some info on it. A schematic, anything.

When searching I lucked upon this, which appears to show a very similar amp, if not, the exact amp but with some mods. This other amp is a confirmed RCA MI-1213 according to the name plate inside. This one isn't mine, someone from Russia:

RCA Photophone MI-1213 Complete Theater amplifier 1930s 45 tubes

I receive the amp tomorrow. So hopefully that plate is visible under the dust inside and I can confirm the model. Will upload better pics the. In the meantime if anyone recognises the amp, or knows where some RCA 1930s theatre sound equipment catalogues or schematics can be found id appreciate any leads.
