Stores Ref. 6D/473 (redesignated 6D/624). This is the later pattern variant of the E-mask complete with anti-suffocation/inspiratory valve and having an elasticated webbing harness. The rubber is in very good condition with only minor cracking around the anti-suffocation valve and very, very minor loss at the edges of the mask in places. The overall shape is also good and the rubber remains pliable. The chamois inner edging is complete and apart from some soiling is in good order. The harness is quite good but rather faded and with loss of elasticity. The press-studded leather section is good.
The mask is fitted with an excellent type 25 microphone (no wiring) and the correct thinner diameter corrugated rubber oxygen tube. The tube has cracking within the folds but is in sound condition complete with bayonet connector/crocodile clip (some surface corrosion). The upper spring clip fastener is missing. Good '+' to very good used. Stock code O15346.
