By The Acushnet Process Co. Dated 4-42. Standard size. This is the first pattern A-10 with the unique and distinctive integral forehead strap running from the body of the mask between the eyes and up towards the top of the head. It also had enlarged 'cheek' pieces covering more of the wearer's face thus providing greater protection. The overall appearance is very good and the rubber is quite clean. There is some stress cracking around the harness mount lugs on both sides of the mask and the nosewire has come adrift at one side. The unique forehead strap remains in place and the oxygen tube is in very good condtion. The webbing harness is clean and the metal componants are free of tarnishing or rust. These early production masks were only made for a limited time soon being replaced by the A-10C (C = Converted - basically modified A-10 production masks with the unique strap removed) and later the A-10R (Revised) produced with a smaller facepiece and no strap at all. Also comes with a webbing 'Juliet' harness to enable use without a flying helmet. This is undoubtedly one of the rarest AAF masks to find. We haven't had one for over 5 years. A good used example.
