Original U.S. Vietnam War Era HGU-26/P Flight Helmet with PRU-36/P Double Visor Flight and MBU-5/P Oxygen Mask Flintlock Muskets and Rifles perhaps of Chinese originOriginal 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.
