[Milsurplus] Equipment ID? Navy, pre-war?

Nick, the big beast is a receiver? It seems to have a lack of the knobs you'd expect on a receiver.
The lefthand box, the louvers would seem to tell me it's a transmitter, and it kinda looks early Collins to me.

>What is the unit on the left in this photo? - connected to a feedthrough on the window.
The big receiver in the center looks like an RAB.
