British RAF A-13 Oxygen Mask

The British RAF A-13 Oxygen Mask is a piece of aviation equipment used by the Royal Air Force primarily during the 1950s and 1960s. Designed for use with high-altitude flight helmets, the A-13 mask provided pilots with a secure and efficient means of receiving oxygen at altitude. The mask is constructed from molded green rubber, featuring a web harness for head attachment and adjustment. Integral to its design is a metal microphone housing mounted at the front, which allows for clear communication within the aircraft. The oxygen hose, reinforced for flexibility and durability, connects the mask to the aircraft’s oxygen supply system. The A-13 model represents an improvement over earlier oxygen mask designs, offering better fit, improved comfort, and enhanced sealing against the face. This mask is representative of British aviation technology used during the early Cold War period and was typically paired with flying helmets of the time, such as the Mk2 and Mk3 series.
