Type A-4 low pressure cylinder with attached type A-13 regulator, together making a complete unit, AN6022-1. One of these assemblies would have been available at each crew position within a bomber or other multi-person aircraft. The crocodile clip on the back of the regulator enabled the bottle to be attached to the user's clothing or parachute harness without the need of a separate harness/sling. This allowed the crewman to move around the aircraft and away from the fixed oxygen point within the aircraft. The cylinder is in quite good condition but does have some minor loss of paint and corrosion. The regulator also has some loss of paint & alloy corrosion. The glass cover on the guage has a crack and the scale beneath has been lost. Good display piece. Stock code O17507.
