This is the type of picture I'm looking for. The equipment in the top of the rack is the SCR-274N Command Set consisting of 3 receivers, 2 transmitters, the antenna relay, and somewhere is the modulator. What is unseen is the transmitter and receiver control boxes in the cockpit. I have located this picture on the internet but I don't know what tech manual it is out of.
The large set beneath it is probably a BC-191, or possibly a BC-375, and along with the set on the table, which is probably a BC-312 or BC-348, and the tall box under the table, the antenna tuner, made up the SCR-287 Liaison radio system for long distance communication.
