RAF oxygen mask tube/connectors - early
Standard early war pattern corrugated rubber oxygen tube complete with a brass plated Air Ministry MK.IV (6D/526) bayonet connector and cadmium plated crocodile clothing clip. These early tubes are significantly narrower than later war examples and were standard fitting on the E-series masks and also used on some early issue G-masks. This example is fully flexible but has some cracking within the folds/corrugation (see photographs). No major splits or holes and in good used condition overall. Significantly rarer than the later war tubes. Stock code O23420.
