Size medium. Dated 4-45 (April 1945). Rare wartime dated example of this otherwise relatively common mask. The rubber facepiece retains reasonably good overall shape but the lower edge is curling inwards. The rubber is quite pliable although rather grubby. On the plus side there appears to be no cracking and only minor crazing when flexed. The pearl grey suede lining is complete but dirty. Fitted with a type 57 microphone assembly and a black flecked light tan coloured loom with the correct large 2-pin socket, type 614, 10H/18196. Note that the microphone has paint loss and the loom braiding is fraying at the upper end. The webbing harness is a bit dirty and lacks elasticity but is complete. These late war H-masks are very difficult to obtain in any condition and are considerably rarer than the G-type mask. A reasonable used example that could be improved significantly with some careful cleaning. Stock code O18719.
