I picked up an beat up old Winchester model 1897 shotgun, and I was wondering what I should do to restore it? Or if I should leave it as it is? It seems to be in good working order but most (almost all) of the bluing is gone. Has a little lite rust here and there. The stock/fore end should also be refinished. I am not very familiar with this particular shotgun so if anyone had any tips for me it would be appreciated!
