Canadian MS-22001 Oxygen Mask

Early 1980’s date made of Silicone. Mask is in exceptionally good shape and has all valves and anM-32B/AIC
Microphone. This is a low 1980s dated silicon mask in exceptionally good condition. I would say unissued or
very light use. M-32B/AIC dynamic microphone is standard AN/AIC-10.
The connector shown in the image is a Criss-Air (or Sierra) 3 pin friction-lock oxygen
connector, typically under part series numbers like Sierra 224-29 (or equivalent 224 series variants).
Not fighter use. Used in trainer and emergency mask in other aircraft.
This would be used in trainer aircraft and other non-fighter aircraft.
