After seeing many pictures and listening to comments I believe that someone has stripped the metal of any finish.Some do appear to have been bead blasted witch I should have seen earlier.                                                                                  
         Until now the only Krag that I could compare it to is my fathers sporterised 1898 rifle that I refinished 35 years ago after my father past away.                                                                                   I think now that I am convinced that the finish has already been stripped that I would like to refinish to as close to original as possible.                I am a commercial artist and have some metal finishing experience and have been asking my son to find me a project gun to restore that was beyond one of his normal m[l[tary surplus rescues.                                                                                  I have been researching rust blueing as finish on blued parts .
