Rare oxygen tube specially designed for rear gunners with more exposed crew positions. Manufactured in thicker rubber less prone to freezing these look almost indential to the standard tube but can be identified by the 1" white band painted around them. This example is in quite good condition. It is a bit grubby but has no major cracks or splits bar the usual cracking within the folds/corrugation of the tube. The lower end has been cut slightly (no flange) such that the brass MK.IV bayonet connector is pushed into place and not bound. The upper connector is not bound in place either but thids could be done if desired. The white band isn't terribly obvious due to fading and soiling (see photos). Reasonably good overall condition. Stock code O19745.
