Code: O7641
Size medium. Dated 1/62. Fitted with the earlier type 57 microphone and the adjustable metal 'horseshoe' harness for use with flying helmet hooks (G-helmets/bonedomes). There is no exhilation valve fitted to this variant. The rubber is in very good condition with only a little cracking on the harness retaining lugs. Some surface crazing visible when the mask is flexed. Reasonably clean externally and the pearl grey chamois lining has only light soiling. Part of the plastic microphone surround is broken (see photo) but the loom, socket and harness are all good. Similar in design to the H-1A mask in having the metal suspension mechanism but differs due to the lack of inspiratory valve in the cheek section. A good/ good '+' used example of this less common Type H variant retaining very good overall shape. Stock code O7641.
