RAF aircraft, air crew oxygen economiser.
This unit was an improved oxygen supply system to the pilot/air crew. Rather than having a constant flow, as in early wartime aircraft using D type oxygen masks. This system gave oxygen on demand, therefore preventing wasting the limited oxygen supply. It would have be used mainly with the G & H type oxygen masks.
