RAF type C carbon microphone
Stores reference 10A/9004. Often referred to as the 'Microphone, mask, type E' (ref. 10A/9003) but technically that refers to the microphone complete with wiring and plug. The microphone consists of a bell-shaped, chamois covered, black painted alloy 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 there is a toggle switch at the top. This example is in reasonably good condition retaining approximately 75% of its original chamois. The loose edges could be glued down in places providing even more coverage. There are remnants of the original wiring loom visible where it is bound to the wiring anchor bracket (bracket screw absent). These microphones were used with the cloth type D 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. Quite a rare find these days. Stock code O16550.
