Does rebluing harm the value of a Pre-64? Someone told me it would. I have a 1947 M70 Alaskan in 30-06. The stock needs to be re-done, and that's all well and good, but the metalwork is weathered as well. I kind of like the look of it, but I want to maximize the rifle's health as well as it's value.
Anything you do to alter it devalues the gun in terms of collector's worth. That includes shooting it. It's an individual decision for sure.
