The Mk.1A was issued in the early 1950`s and was the first RAF helmet with a fixed visor, the visor locked at various positions and was issued in various tints from clear to dark tinted. The RAF Mk.1A Flying Helmet superseded the Mk.1, this having a separate visor fitted by elastic straps. The Mk.1A was originally used by all front line pilots flying rotary & fixed wing aircraft, this included subsonic & supersonic aircraft, everything from early Hunters to Lightning's and continued in limited use until the late 70`s and finally used by training squadrons (EFTS/UAS) until the late 80`s. Although designed to be used with the G-Type Helmet and H-Type oxygen-mask, the helmet was also used with the A-13 oxygen-mask & later the P-Type oxygen-mask. This later usage with the P-Type mask caused wear & tear problems to the helmet edge roll due to the protruding P-type mask fittings abrasing the helmet leather lining & rubber edge trim. The Mk.1A was originally issued in a silver colored shell, but later examples were issued in matt Green or Grey. The helmet is leather lined with a non-adjustable webbing harness.
