[Milsurplus] EG-3 motor generator set for ??

[WA5CAB--- via Milsurplus]

That was it's primary operating mode, batteries for the receiver and 
hand-crank generator for the transmitter.  Same as the Signal Corps BC-654 and 
BC-1306.  But like those sets, it might also be used in semi-fixed forward 
locations and in vehicles.  Like the two Signal Corps sets, it had a gasoline 
powered generator (the EF-(*) that ran the transmitter while the receiver 
remained on battery.  And it had a veritable forest of outboard power supplies.  
The receiver ones came in six flavors, 6 VDC, 24 VDC, 32 VDC, 12 VDC, 115 
VDC and 115 VAC.  With the latter three being available for both the TBO 
through TBX-6 and the TBX-7/8.  The only ones I have ID'd for the transmitter 
are 12 VDC, 115 VDC and 115 VAC.
