USAAF A-9 'Short' Oxygen Mask. By The Acushnet Rubber Co. Dated January 1942. The rubber facepiece is soiled but generally in good flexible condition. There is only minor cracking/crazing, a small repaired split at one edge (see photographs No.8 & 9) and a little distortion at the nose. The nosewire is absent and the two side retaining lugs are split. The attached corrugated oxygen tube is generally in good order. 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 good example. Stock code O23474.
