ID this old RCA(?) tube amp?

Got this tube amp in. It maybe is an RCA of some type, but looking for exact model so I can find a schematic.

I don't think it's RCA. You typically see vent holes drilled around power tubes on those type RCA chassis.

Can we get a gut shot? Or any knobs on the front?

The face is some custom job with volume knobs and power switch. No helpful info. Here is the inside

This does not look like typical RCA construction to me. Even their PA amplifiers had a nice ground bus bar running the length of the chassis.
