We thought we would never get any more of these but after several enquiries we have managed to source a few more. These hoses are identical to the genuine article (we have one (not for sale) for comparison) and were used during WW1. The rubber hose came in between the wars.
The hose has a screw thread connector. It can be fitted to the gun once the adapter boss has been unscrewed (this adapter is the part that was fitted to allow the rubber hose to be clipped on). All Vickers guns have this adapter screwed on as it simplified production of the WW2 guns.
Photo is for part identification only and does not show the actual hose.
