USAAF A-9 'Short' Oxygen Mask. By The Acushnet Rubber Co. Dated January 1942. The rubber facepiece is in excellent flexible condition with only light soiling/wear. The nosewire remains in place and there is no cracking or crazing at the retaining lugs. The attached corrugated oxygen tube is equally good and has the standard quick release fitting. The webbing harness retains good colour and is fitted with metal plates designed to attach to the hooks on teh A-9 or B-6 helmet. This example also comes with an excellent webbing 'Juliet' harness enabling the mask to be worn without a flying helmet. The A-9 is a relatively rare mask as they were only produced between 1942 and August 1943. An excellent example. Stock code O21234.
