Rare US Navy Flight Helmet VMSB-231 ID’ed Marine Scout-Bombing Squadron 231

US Navy summer flying helmet type M-450-1 with receivers. Rare example ID’ed to PUCHEU, a member of Marine Scout-Bombing Squadron 231. This unit took part in the battle of Midway and Quadalcanal. The helmet is a early M-450-1 with rubber earcups and TH-37 receivers with rubber wiring loom. The chinstrap and buckles are in very good condition. Very nice and rare flight helmet that would be a great base for further research!
