An original example of the later pattern, unbraided, all rubber 5 foot long oxygen hose and 6D/101 connector for the D-type oxygen mask. The tube is still full length although rather distorted and bent with surface cracking/crazing. Some of this distortion might improve with careful application of heat (buyer's risk). The 6D/101, MK.IIIB* connector is clearly A.M. & King's Crown stamped with a 1939 date. Extremely rare to find in any condition. Stock code O16155.
