Size Medium. Dated 4/54. Fitted with the type 57 microphone as used in wartime dated examples. The rubber is in excellent good condition overall but does have some cracking around the harness retaining lugs and expiratory valve. The lower edge of the mask is folding inwards but can easily be reshaped and show no sign of perishing or cracking at this point. The brown chamois lining is reasonably clean. Fitted with a decent, clean harness that retains elasticity. Excellent microphone, loom and socket. A good used example. Stock code O18213.
