This is a nice clean original B8b WWII High Altitude Oxyen mask set. The mask is nice and pliable rubber with the original straps but with breather bag being a perfect replacement as the original was missing when we got this mask. The attatching hose is broken and a bit stiff but likely salvageable. The item "Original World War Two U.Army Air Forces B-17 bomber style A-8-B Oxygen Mask" is in sale since Sunday, May 26, 2019.
