I have seen that but it doesn't help as I can't work out which wire goes to which ring. There is a different colour dot by each wire so I was hoping someone would be able to tell me which colour dot goes to which ring???
I'm surprised there isn't a standard connector by now. See image below of a Mk4A helmet. When introducing this, I wanted to use a 9 (I think) pin "snatch" connector, used by US Apaches. This met the UK spec for pull weight on emergency egress, which is about 8lbs.
I was told "No" in no uncertain terms by OR so had to go for what you see. They are staggered so one pulls before the other, to meet the 8lb limit. Also, you can perhaps see each is a different diameter, so you cannot mix them up in the dark, and the smaller one has a different sleeve length (the bit furthest from the tip). This was to avoid shorting as you could get this one in the others female socket, but not vice versa. Hope that makes sense.
I seem to recall the UK NATO connector design dates from about 1947, and originals remain in service!

Thanx 4 the diagram, that's what I was looking for.
Probably won't work but I'm going to wire the modern jackplug into a socket that that huge plug on the C-Type has to see if it works.

Hi Alexis
your usual problem is impedances, particularly the mic. Really old headsets have carbon mic.s; an electret mic prends to be a carbom mic in a sort of way, and adjusting mic gain can often give a usable result.
Later 'massive' jack plugs (see Coffman stater's post) use the same colour code as my diagram.

I helped to modify a C type for the BoB 70th anniversary airfield tour, but used a modern headset from a MK.10C / Alpha type helmet. The transducers were a pain but the rest was simples.
