Portable oxygen was used by aircrew when working away from their normal crew positions. The oxygen was supplied in black painted steel cylinders providing 10 minutes supply. A gauge at the top indicated the amount of oxygen remaining. Various stamps, contract/reference numbers are marked on individual parts ranging from 1944 on the cylinder itself, 1943 on part of the valve and 1954 on the gauge. This example is fitted with a clothing 'clip' (stores ref. 6D/1280), enabling the cylinder to be attached to the parachute harness. There is some loss of paint on the cylinder but overall condition is very good. These make an excellent display when attached to the oxygen mask via the tube (D-mask) or extension tube (E/G/H-masks). Please note that this item is very heavy and due to postage restrictions on such items cannot be posted overseas. Stock code O19444.
