USAAF A-9 'Short' Oxygen Mask. By The Acushnet Rubber Co. Dated January 1942. The rubber facepiece is soiled but generally in very good flexible condition. There is minor surface crazing/cracking on the facepiece and the nosewire lugs have perished leaving the wire loose. That said there is no serious damage to the mask. The attached corrugated oxygen tube/connector is in very similar condition without major issues. The webbing harness is a bit stained but retains good colour and is fitted with metal plates designed to attach to the hooks on the A-9 or B-6 helmet. The A-9 is a relatively rare mask as they were only produced between 1942 and August 1943. A good example. Stock code O22903.
