Classic pressure demand mask with a green rubber facepiece and fibreglass 'exo-skeleton'. Fitted with horse-shoe clamp harness and 'link-chain' fittings. The rubber is in excellent flexible condition. Good exo-skeleton and harness. Fitted with a plastic amplivox 13100 microphone/loom and multi-pin Socapex connector. The corrugated rubber oxygen tube is fitted with a push-fit alloy connector. The Q-series mask is essentially the same as the type 'P' but smaller. The different designation was allocated simply because the contract was awarded to a different manufacturer. This mask should fit the MK.4 and ALPHA MK.10 series helmets. A really good example.
