Picture attached of the inside of the base of the centre tube. Unfortunately whoever unscrewed it before me took the brute force and ignorance approach.Mark . Do you mean that Z mark that is inked on the side or is there one stamped on the inside of the threaded portion ? That's not a zinc alloy tube & in any case the Z mark only appeared after 1939 so never appears on WW1 ordnance . There is a thread somewhere on BOCN that I posted some time ago about WW1 Mills centre tubes . The No5 tube will fit a No36 but look incongruous . Can you post a scan of the inside lower part ? The No5 tubes have a ridge around the striker pocket & the No 36 tubes are flat .
Cheers,
Mark
