Hello, FYI, That fine looking receiver is an RBB, one of three in a series that covered from approximately 10 kHz through just a little above the current Citizen's Band, probably 27.5 MHz or so.
The RBA covered from approximately 10 kHz - 600 kHz. The RBB covered from approximately 600 kHz - 4 mHz. The RBC covered from approximately 4 MHz - 27.5+- mHz. As I recall, each receiver covered it's tuning range in four bands. I owned a RBA and still own a RBC. An article in either Electric Radio or Antique Radio Classified said the RBC was the most expensive short-wave receiver ever made up to that time. My RBC is dated 1943. I am dated 1942. It's 1942 dollar cost was approximately $1600.00 in 1942 silver certificate dollars. The local oscillator in those super-heterodyne receivers actually transmitted a small signal 455 kHz above or below the receive frequency ( I think 455 kHz was the RBC i.f. freq ). Because of this, the German and Japanese submarines could tune around for the unwanted radiation from our receivers and direction-find the ship in question whose receiver was radiating this un-wanted signal so it could be df-ed, located and sank. They could also tell what frequency we were monitoring. Part of the expense of the RBA - RBB - RBC receivers was the excellent shielding that was used internally to reduce this type of radiation.

I was aboard the Texas for the Dec. 2015 remembrance of Pearl Harbor and activation of the Texas radio event. At that time the radio room was off limits to the public. The Ham Radio activation was from a compartment a deck or two above. Good to see.
