Corrr, didn't think there were many of these things left...may have to go and have a look-see. Is it complete?
Think so. Chatted to a bloke at Beltring once who had one and all the different sorts of ammo - said the ammo was worth considerably more than the Gun. Thinking about it, it may have even been this very gun. There's one at Woolwich, but it might be an odd variant - can't remember.
