Unlined pale green cotton mask/hood for use with a flying helmet and oxygen mask. Almost certainly manufactured by Windak. In use this was held to the early pattern C-type flying helmet using the front goggle straps and press studs to the rear. Fitted with an Air Ministry stamped zip fastener to one side for a snug fit and has a hole at the front to allow an oxygen tube to pass through. Light soiling, otherwise in excellent used condition. Pictured in Mick Prodger`s Vintage Headgear book, p.205. Intended for use by rear gunners in particular although these appear to have seen limited service use. Stock code H14383.
