Have it rebarreled with an exact copy sans the markings save the old barrel.it can be polished around the stamping plus there's a fellow out west that reingraves rifles I can try to find his no. If you get it reblued tell them not to polish the whole rifle just the offending area.and do a blackish military style blue not the colt python polished.just had a model 70 done it was done back oraginal look a matt like finish.im looking at a mannlicher locally if I go for it was going to have my friend duplicate the barrel only in 318 Westley Richards.have too many 3006 now.just save the barrel for resale.
