> It was thought to be a SCR 595   Not sure?

Fred Chesson's site says that the BC-1293 is part of AN/CPX-1, an air-transporable
Mark III IFF interrogator system.

The SCR-595-A is the most common Mark III *aircraft* transponder.  It
actually has USN nomemclature as the ABK-*, even in USAAF service.  It's
about 35 pounds and, of course, much much much smaller than the ground
interrogator system.  The other common WWII IFF transponder was the SCR-695-A,
(BC-966-A) which was a Mark III/G IFF.  Anyways, what you have is neither
of these.
