The exterior only has very minimal wear and shines. Complete with receivers, avionics, padding and chinstrap.
I cant find a specification label inside but the helmet but I estimate the size to be large and is the early type which were only produced a couple of years in the late 1950s and early 1960s. I wear a size 7 ΒΌ and it fits me easily.
This is a very hard flight helmet to find in flight helmet collections. I have included an original postcard showing two pilots at Eglin Air Force Base wearing this type flight helmet. Minimal wear and great for early USAF flight crew displays. The item "1950s USAF Air Force F-100 Super Sabre HGU 2/P Jet Pilot Flight Helmet (large)" is in sale since Monday, August 5, 2019.
