Ok, I'm a collector of esoteric relatively inexpensive anything that shoots. I've found a French 1935-A pistol that is in good working condition but looks like it was stored in a blender set on frappe. The original finish was goofy to start with, black enamel over parkerized. Really ugly. Now, it's scratched up enamel over parkerized. The only thing that I think that could be done would be to strip it all down, polish out or bead blast it, and blue or parkerize it. That would destroy any collector's value. The collectors value being, what? Maybe $500 to a french loving lunatic on a good day? That's today of course. Tomorrow, who the hell knows? It would likely cost me a few hundred bucks to have it refinished.
