A refinished Parker VHE 28 ga. is what it is and should be valued as such. As KY Jon said, it all depends on how well it was done. I think it is a dirty trick if someone tries to pass a refinished gun on as high-condition original, though most experienced collectors would be able to determine a refinish from an original. A lot of guns got pretty beat up and worn from decades of field use and a VHE was made as a field gun, so its refinished condition may be worth a hell of a lot more than what it might have been before refinishing. The only reason (in my mind) to refinish a gun is if it is just plum worn out and used up.
