I purchased two old military headsets that

these working (being compatible with civil radios)?

I haven't got a clue :-)

Common sense sez the equipment has to fi together in the mechanical
sense, meaning your plugs would have to match at some point, and the
equipment has to match in the electrical sense, but since I've no idea
what the specs are on either end of the system, I've no what you would
need to 'get these working.'

Using new/surplus ear-phones and mikes to make-up headsets that will
work with the typical Icom or Yaesu is duck soup compared to getting
two antiques to talk to each other. I've seen some comm gear that
still used the PJ-068 jacks & plugs -- stuff that dates from the
1890's(*) -- being copied and fosted off on innocent airman because
"We've always done it that way' or other non-sensical reason, as if our
next flight will be in a 1937 DC-3, complete with its Detrola radio.

(*) -- During the early days of telephone expansion there was some
serious competition between Ma Bell and honest people. The 7/32" phone
plug came into existance during this time (I think it was introduced by
Stromberg-Carlson). Later, it was used by Collins as their microphone
plug.
