I've come accross a few No 4 and No5 rifles that have had the original serial numbers Xd out and another number stamped on the buttsocket. I'll breifly describe a #5 that I have. It is etched on the flat No5Mk1, ROF(F) 3/45 with a "K"series number that has been over stamped with Xs. A "G" series number has been stamped into the buttsocket. The forestock also has the same number stamped into it. It has a second variation bolt that is stamped N S H 5 in the lightening cut on the reinforcing lug and a strange P20001A stamp on the bolt handle which also has a large 26 etched underneath. The bolthead is a 1 and is etched with the crossed flag symbol and 31. It's obviously a rebuild, but a mystery as by whom and why the reserialiseing. It will always be a mystery but any comments and opinions would be appreciated. Sorry I can't send pics.
