Hi all, Among the pictures that SIWA sent to me was one of an olive drab P-3 helmet with orange visor yoke. Also a very interesting (am I saying that all the time, a thesaurus please) helmet because it has some typical P-4 features (visor yoke with long-throw J-arms and black pigtail comm cord) at first glance but the earphones are attached in P-3 fashion, tied with nylon cord through two small holes in the lower cheek area.
Cheers,Bluelight
