[Milsurplus] [MMRCG] mystery socket

[Steve Haney]

I am looking at one of the connectors from the PRC-25 and -77 battery and
it has a "D" cutout in the center of the five hole.  Also only 3 pins and
they may not be in the correct places for a different application.
Otherwise it looks very much like the picture above.  Rivets and holes all
in the same places.  1-1/2 inch by 7/8 inch.  But no idea what they are
called.  Thanks, Steve
