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. The actual microphone is mounted within this (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 reasonable condition. The carrier (shell) is a little distorted around the edges but being alloy, this is quite easy to reshape. The switch has been broken and the microphone retains approximately 40% of its original chamois. Remnants of the original wiring loom are visible and the wiring anchor bracket is present although not secured/screwed into place. 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 O16654.
