Size medium. Dated 1/80. Fitted with the smaller plastic Amplivox 13100 microphone and 'quick disconnect' (QD) loop harness loops for use with metal oxygen mask hooks. A standard elasticated webbing harness has been accommodated by reversing the QD loop and utilizing the 'closed loop' side of the fitting. The rubber is in very good used condition, supple, reasonably clean, with only minor crazing around the microphone and on the harness retaining lugs. The elasticated parts of the harness are also very good and the pearl grey suede lining is quite clean. A very good example of this less common Type H variant. Stock code O25091.
