Stores Reference 6D/644. Size small. The rubber is a little soiled but is reasonably supple and the overall shape is very good. The mask is 95% crack free but there is some cracking around each of the side nosewire lugs and inspiratory valve. The centre nosewire lug is undamaged. The edges of the mask are a bit mishaped with the lower section folding inwards slightly. The harness is faded and lacks elasticity but does retain all three original elastic bands. One of the harness press studs has been replaced. Lined in pearl grey suede, this is complete but rather grubby. The mask is fitted with a type 48 microphone assembly (type 25 microphone, loom and socket) complete with internal anti-freeze gauze plate. A very good used mask. Stock code O22080.
