Stores reference 6D/644. Size small. The rubber is quite clean, supple, and the overall shape is very good. The mask has relatively minor cracking around the microphone retaining ring, inspiratory valve and nosewire/harness retaining lugs. The lower edges are curling inwards a little and there is a small reinforcement patch on the inside at the nose, these look far more significant in the photos than they really are! The harness is a bit stretched but retains a little elasticity, some colour, and all three original rubber bands. Lined in lovely clean tan suede. The mask is fitted with a very good type 48 microphone assembly (type 25 microphone, loom and socket). A good/good '+' used example. Stock code O18398.
