Military stuff?
Many companies stopped making items after WWII, partly because there was no need, and also because some were pressed into making things they did not normally make, and they went back to peace time production.
General Motors made M16 rifles during the Vietnam War, for example...

I'm curious about the device on the side, is it maybe an old style divider string or is that an air variable?
Wondering if it could be an air capacitor, I've seen some before, but not exactly like that. Perhaps there's a diode connected to one pole underneath there on the 1st picture. Could it be a smoothing circuit for the transformer on the other side?
At any rate:
Epic (Or perhaps "Epoch") find there Brandon, very intriguing.

The original advert markets it as a top "hi-fi" speaker. The past owner has it scanned on his pc
Also, the unit weighs 24kg. It is a monster. Sheepskin surround, with paper cone. Will post frequency graph (the original, and advert) later. Will find out re: the above questions, to see if I can find the satisfactory answers.
That's probably a copper oxide rectifier (don't know the specific term in English, in German it's "Kupferoxydul-Gleichrichter"), predecessor of selenium rectifiers.
Interesting. It's clearly a speaker with an electromagnetic motor, never seen these days with the powerful neodymium magnets that are available.
