Up for your consideration is this WWII United States Army Air Force bailout out oxygen bottle. This bottle is made by Ohio Chemical Company of Cleveland, Ohio and is green in color. This is the earlier version with the manually operated valve for setting the oxygen flow. The bottle still contains some oxygen and if you open the valve slightly you can tell that it's still charged! It has a rubber hose with the end fitting that would go into the mouth and is dated 12-42. Both hose and mouth piece are in excellent used condition. The canvas carry bag is marked: U.S. AIRFORCE BAILOUT BREATHING OXYGEN DWG. NO. 42G7365. There is a small tear on the bottom, however this does not detract from the outward appearance and the bottle is still secure in the bag. I previously had this bailout out bottle in the leg pocket of and early bomber display and it looked great. Please e-mail any questions which you may have. Thanks for looking!
