RAF, G Type oxygen mask microphone anti freeze cover.
The anti freeze cover assembly type 4 was fitted to the type 26 microphone usually associated with the type G oxygen mask. It consists of a transparent insulating disc, 10A/7066, a metal gauze cover 10A/12925 and a retaining clip 10A/17025.
At very low temperatures it was found that the microphone froze and interfered with it working. This simple modification helped to prevent such a problem.
It is in very good 'used' condition.
