Item Description
Original Items: Only One Available. This is a very nice 1956-1964 USN size MEDIUM Gentex H-4 helmet that comes with B-8 goggles and an Large Summer Flying Helmet by Gentex. 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 interior has the name SIGMAN written on it and we believe this to be for Lieutenant Colonel John P. Sigman, a veteran combat pilot from WW2 who served with the 1st Marine Helicopter Squadron during the Korean War Era. We cannot confirm that this was his helmet due to just a last name being present.
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. This was secured to the rigid shell by "pull the dot" snap fasteners on the cheek flaps and in some cases with additional straps attached to snap fastener in front and in the back of the rigid shell.
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.
