Standard wartime pattern corrugated rubber oxygen tube complete with screw-threaded top connector for attaching to a G-type or H-type mask . Fitted with a brass A.M. marked MK.IV bayonet connector and 'crocodile' clothing clip to the bottom of the tube. The hose is in very good condition with no sign of cracking or perishing. Connectors are attached with metal circlips so this is probably early post-war. Stock code O16546.
