Very Nice Mr E, Looking at the nose cap its had a bayonet on off a few times ? all the info I had gained on the No1 MkV has long gone (memory stick failed, lots of other stuff gone too...) I cant even remember what I sold my complete one for, Still have the one I saved from a Sporter though, there was one in the UKicon for a very overinflated price tag some time back, which was the one I seen many years ago in an auction it never reached the reserve of just over £700 but it was an mint example, (not to be confused with the one that was doing the rounds which was done by EFD, only original part was the Action)
Think the last original one I seen went for around £1500-£1700 in the UK.
