Size medium. Dated 4/51. Fitted with the earlier type 57 microphone and standard webbing harness. The rubber is generally sound and very supple but does has some cracking around the microphone retaining wire, anti-suffocation valve and harness retaining lugs. There is also stress crazing around the lower edge area but the mask retains good shape and is reasonably clean inside and out. The harness, microphone, loom and larger WW2 style socket are all good. An excellent wartime 'lookalike' mask. Stock code O20614.
