This is an early USAF HGU-2/P Flight Helmet with MS-22001 Oxygen Mask. The Helmet is in great condition and fits like a size medium. Early push button visor control and leather mask tabs. Headphones are complete with all wiring but the pads are’crispy’. Styrofoam liner and leather covered foam sizing pads are good. The nose cut in the visor looks like its for a MBU-5 mask, this is the way I recd it. Nice paint and USAF decal! The mask though, is a little rough. The hardware and straps are in great condition, the microphone/wiring and valves are intact but the mask body has some cracking/loss and the plastic nose bridge has a crack. The hose has some cracks but is in fair shape. It has a bonus detachable CRU-8/P connector block at the end. Ships to US ONLY at 5lbs 5oz.
