What ever is on the rifle when it left service is correct. There is no factory correct in the Enfield Line of rifles they are battle rifles not prima donnas. If you find a rifle in mint condition it has not been there or done that which is what a battle rifle is all about the scars tell a story as do the FTRs and replaced parts. Enfields that are beat up look tired or ratty have been there done that and are worth more because of that.
