I am not sure who made the barrel, but it is the same one I have seen on the mod 455 Marlin, and also on the Montgomery Wards mod 760 EJN that my son owns! I have found that the barrel needs to be cleaned more often and my experience with it is that it is picky with some loads! It by the way, shoots my loads at less than an inch.
This rifle you are selling is easily one of the finest examples of one of the commercial mausers around and I think it is worth the money you are asking. I don't have the money--but if I did!!!
