Vinegar will remove the bluing - that is what my engraver friend uses to strip blued guns before they are engraved... They look just like your gun once they are stripped. Since there is no original finish on that beauty, it is now a perfect candidate for an Oscar Young pattern engraving project. If it were mine, it would be on the way over to Phil Quigley as we speak with photos of Oscar's work as an example of the engraving pattern I would like cut.
