Full description:

A modified RAF H-type green rubber face mask, with chamois leather-lined cheeks. It has five spring-loaded inlet valves (three with metal and plastic fittings and two with black plastic fittings on the outside, and all with black plastic plugs on the inside), 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 'MEDIUM'. 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 (not present).
