HGU-2A/P with Ramshorn double visors Original good used condition. Helmet size Medium, mask Long Narrow. Missing front interior pad and foam in ear cups. Both Sierra and Gentex introduced double visor assemblies for the HGU-2A/P helmets in the 1960s. Due to their construction they are colloquially known as ramshorns visors, a term that was actually coined by the inventor of the concept, Sierra Engineering (see the ad below). Sierra’s visor housing was made in one piece while Gentex’ housing consisted of a separate center visor cover and two visor housing extensions for the visor lock knobs and actuating rods. Consequently the two visor types are referred to as one-piece and three-piece ramshorns visors respectively. The two visor types were never adopted as military standard by USAF and therefore did not get any military designation or stock numbers. However, used in quite large numbers by USAF aircrew. Modifying an HGU-2A/P helmet with a ramshorn visor did not change the helmet’s designation either. It was still an HGU-2A/P. The visors were, however, mentioned in the USAF Technical Orders as being commercially available. Please check out our other Auctions.
