That thing pre-dates the BC-1F IOW, pre-1950.
Looks like it used one of those large James B. Knight
rectangular black bakelite ovens. This is old, old.

It's a VU meter panel with non-standard meter attenuators.
Not Weston meters, these look like replacement Simpsons. 
They appear to be the same meter used in the tube type
Gatesway board mounted behind the panel so you didn't see
the meter case.

I think I see "Cinema Engineering Co. Burbank" there. The 
standard meter range pads went to either +34 or +39. It 
looks like the meters were replaced in the late '50's or 
early '60's before Simpson converted their VU's to the same 
"open top" case look at their DC meters. The wiring looks 
like late '40's I'm guessing it originally had Weston meters. 
Which Plough station did it come from?
