Stores ref. 10A/9004. Many of you will probably know this as the Microphone, mask, type E (ref. 10A/9003) but technically that refers to the microphone complete with wiring and plug. Anyway, the microphone consists of a bell-shaped, chamois covered, black painted brass carrier. Within this the actual microphone componant is mounted (10A/7355). Part of the inside of the carrier is sprayed with powdered cork which acts as an insulator against condensation and noise. To the base of the carrier are two moulded breathing vents and at the top is the toggle switch. This example is in very good condition retaining much of its original chamois that is marked with the number '53' top one side. I suppose this might refer to 53 squadron. At the time this microphone would have been used that squadron were ar RAF Farnborough with the Hawker Hectors for Army Cooperation; specialising in night reconnaissance. In January 1939 the squadron was given the Bristol Blenheim and moved to France in September. Following the German attack on France in May 1940, the squadron returned to the UK. From here it undertook bombing and reconnaissance missions. There are remnants of the original wiring loom visible and the wiring retaining anchor is present with original binding twine. These microphones were used with the cloth D-type oxygen masks and pre-date the flat-fronted type 18 (type 19 when mounted/wired). Photographic evidence suggests they saw considerable use during the Battle of France - for example with 53 Sqdrn. This example has the earlier/heavier brass housing. Later microphones had a much lighter alloy housing. Good looking microphone and a rare find these days. Stock code O16565.
