Original Vietnam War MS 22001 Pressure Breathing Oxygen Mask w/mic 77-79 Med

Description

This is an original, US military contract MS-22001 Pressure Breathing Oxygen Mask as issued to American air crews during the Vietnam War and immediately after. Has an intact microphone, but I have no means of testing whether that is still functional. What you see in the photographs is what you will receive. Hose is obviously missing, but the communications cable is still atached. Otherwise it looks like it is complete based on photographs I have seen. This is not my field of collecting, so if you have specific questions please make them clear and easy to understand. Size Medium. Made by Sierra Engineering Co. I believe this was made between 1977 and 1979. Overall condition is very good, although it has some patina on the metal parts and a bit of soiling from poor storage over many years.
