The armour cable snaking up from behind the 2x4's supporting the battery box trays is the standard (common to all 2K1's and 2K2's) Grant Battery feed for the optional Onan Generator installation. It will end just in front of the Wireless Operators seat with a slim rectangular electrical box, the cover plate of which should have a central hole with the two (+ & -) wires hanging out. On the floor of the wireless box in that area should be four holes in a large square pattern, where the tray or box for the Grant Batteries was mounted, or if one is lucky, the tray itself. Most seemed to disappear outright, probably because they annoyed the hell out of the Wireless Operator, if they were not being used.
I covered the Grant Batteries in another post somewhere here, but cannot recall which thread.

Maybe this was the wartime NDHQ Smoking Shack, and because it was headquarters, they got to keep the radio.
