Hey folks, first post here. Today at a gun show, I saw an elderly gentleman selling an unusual-looking 3 Screw Blackhawk in .357 Mag. It had the following features: 1) Mint finish-- looked like it was made a couple years ago. Either high-gloss stainless or nickel finish. Gold trim on the trigger, hammer, ejector, and frame screws. 2) I looked up the serial number. Manufactured in 1965. 3) 6.5" barrel (I think) No engraving or anything else. No box or papers. I'm wondering what might the odds be that this piece was factory original? Or is it more likely to have been refinished? Any other thoughts?
