early IR technology is all i can say , i know the CSIRO has books on it , but i forget all the details , sorry
you folks forget how many things we invent here that get taken over and made famous elsewhere
the Seabee's fitted our test stuff to a M1 carbine for use
we did also put it on a garand but the rcoil was too much for the gear so we got a M1 from you folks
we swapped the top illuminator with a US made one but dunno which is in the pic , ours or your..
and it became rather well used at the Chosin reservoir ...
then became another obsolete test that sat in racks to get a clean and oil every 6-10 months
i'll get a pic of it as it is now
