Original U.S. Vietnam War HGU-26/P Flight Helmet with Double Visor, Oxygen Mask and 1965 Dated Flight Suit

Original Item: One-of-a-kind. The HGU-26/P request for nomenclature is dated Jan 14, 1970 and is based on the HGU-22/P Helmet Shell. There is no military specification detailing exactly what goes into an HGU-26/P but until the appearance of the single visor HGU-26/P both USAF and manufacturer information was consistent in describing the HGU-26/P as an HGU-22/P helmet shell with a PRU-36/P side-actuated double visor. Sierra Corp and Gentex Inc sold single and dual visor HGU-26/P helmets.
