Yes.
The plating has to be stripped, the bare steel surface brought back to the brush finish they used on military contract guns (before they started parkerizing) and then blued normally.
It can be done, but it won't be cheap. Back when S&W offered full service, a "change of finish" was about twice the price of a refinish. I don't think they work on guns that old any more. Maybe they would recommend a shop. Maybe somebody here knows of one.
