Coffman,
yes my CONDEC (Consolidated Diesel Electic Co -a division of GM if I recall) pic was taken in the early 70's as you can just see the custard colour scheme. I think it was taken at Boscombe on one of the Heavy Drop Courses.
The chaps in the red berets are from 16 HD Company who rigged the loads in those days. Tech support was from REME. Later on as the Para Brigade contracted and 16 HD disbanded the rigging was done by Air Despatchers of 47 AD Squadron.
