[Milsurplus] Radio in USMC Gun Motor Carriage 75mm M3

[WA5CAB at cs.com]

Mark,

I had originally suggested the TCS.  But the SCR-608 (which could have been 
in the M3's by the time they were retired or converted back to M3A1 Personnel 
Carriers in Europe) is out.  Remember that I had originally said that an 
external view photo of one of the vehicles showed an HF antenna.  Since then, I've 
come across a second one taken on Tinian at the end of July 1944.

Do you have anything that would give a clue as to how/where the GF/RU was 
installed in the M-2-4?  I have manuals on several of the GF/RU and RU.  None of 
the manuals mentions ground installations.  And to the best of my knowledge, 
there was never any local control capability.  I suppose maintenance personnel 
could have lock-tuned the radios and then removed the tuning head.  But that 
still leaves control heads and cabling to mount somewhere.  plus the radios and 
dynamotor power unit.
