One last thing if the barrel or action was not requiring any work including the bolt etc then would they have placed an FTR on the receiver to denote it had been done as I have seen on countless pics of these markings through books and web pics.
Could it be that this weapons action was as described to me by the gunny and just the woods were stuffed and needed replacement anyway it is a good talking point mind you I would just love to go through the Enfield pattern room, have you been through there Peter or anyone else for that matter boy I would just love a tour......
