Full description:

A modified RAF H-type green rubber face mask, with chamois leather-lined cheeks. It has three spring-loaded inlet valves (two with metal and plastic fittings on the outside and black plastic plugs on the inside, and one empty valve), so placed that the inspired air blows over the nose and mouth. There is a hole at the bottom of the mask to take a tube to connect the face mask to the flowmeter, moulded 'DETACH TUBE HERE'. The face masks were available in three sizes – the rubber on this one is moulded 'LARGE'. Grey textile webbing straps pass through rubber loops on the front of the facemask and are secured with safety pins; these are attached to fittings for the head strap. The beige textile webbing head strap would be attached to one side of the face mask with a metal hook and to the other with two metal poppers on a piece of leather.
