I agree with not refinishing/re bluing. It seems like expended time, effort, and money to really get you nothing in the long run. As earlier stated the weapon was not blued to begin with so you would be doing more harm than good. The aged/patina look is certainly right for the age of these weapons and I concur with Paul. Nothing more than a good oiling is really necessary to preserve the rifle and keep it as pure to original as possible. I am a bit of a purist though as a military surplus collector. On a side note, nice work scoring a couple of Krags and a warm welcome to the forum!
