Mask, Oxygen type A-14B. Size medium c.1958. The 14B was the last modification of the A-14, first introduced during WW2. It is very similar in appearance and would make a suitable substitute for those with a tighter budget. Condition is good, the rubber is a little grubby but remains flexible and undamaged bar some surface crazing when flexed. There is minor cracking on the rubber parts of the harness but the webbing components are very good and the hose, complete with MC3A connector shows only minor cracking within the corrugation. Stock code O25065.
