Hello & thank you for looking at my auction. Up for your consideration is this WW 2 or Korean War ?? Air Force Fighter Pilot Oxygen Mask size Large Type MS- 2-2001 MSA 77176 AF S/N 5509 55B3597 Connector type MC-3 in excellent condition i would say. Very clean, all the rubber is still very soft and pliable, cloth straps very sturdy, no fraying. All snaps work. Looks like it was hardly used. The leather cap / hat is also in excellent condition, no rips or tears just a small scratch on top. Also very soft and clean. Size Ex. Large. The radio headset patch cords in excellent condition. I am assuming these items are old, thats what i was told from the person i got them from but not sure. Please ask all and any questions and i will do my best to answer them because i am not sure on these items, never dealt with some thing like this before. Being sold as a COLLECTIBLE item only... Would make a nice addition to your Air Crew Equipment or Flight Helmet collection. Will combine shipping on any auction items i am running. As this is an auction all sales are final so please email me with any questions or for additional photos and i will do my best to give you a quick response. I make every effort to disclose all defects if any that i am aware of. Please email me if you would like a shipping quote. I do not use the automated shipping chart. ... read more
