Original Items: Only One Available. This is a very nice 1950s USN size “Small” Gentex H-4 helmet that comes with correct U.S. Navy Marked “Snap-On” Goggles and a Summer Flying Helmet (Marked size Large) by General Textile Mills. Helmet features original gold and green paint with USN/USMC Aviator wings to front. All parts are in good condition.

This is a very nice display set!

The H-4 features a rigid shell with reinforcing ridges and is constructed of a fiberglass cloth reinforced with epoxy resin. For this model a cloth inner helmet which incorporate the earphones was utilized. The inner helmet which accompanies the H4 is marked: “CONTRACT No. N288s-26302”. It is not the model which features the snaps which connect to the outer helmet, but to our understanding this helmet was used in conjunction with the H4.

The H-4 was often equipped with a boom mounted microphone M-6A/UR to be used below 10.000 feet. Above this altitude an A-13A or A-14 or MBU-3/P oxygen mask were used. Black rubber goggles B-8 with modified straps to be attached to snaps placed on the sides of the helmet shell below the adjustment webbing. The H-4 was used by USN and USMC pilots in the middle of the 50s into the early 60s, and during this time a multitude of different configurations were used.
