USAAF A-9 'Short' Oxygen Mask. By The Acushnet Rubber Co. Dated January 1942. The rubber facepiece is a little soiled but generally in good '+' flexible condition. No damage but there is some cracking/crazing visible when the mask is flexed. The nosewire is absent, possibly never fitted. The attached corrugated oxygen tube is in excellent condition but a replacement and has not been secured with circlips. The push-fit connector is a later period addition. The webbing harness 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 reasonably good example. Stock code O25209.
