I have a plum-colored Iver Johnson model 822. I think most people assume that because the patina is changing to this color that the firearm has been re-blued. I had a Dan Wesson revolver that had turned plum-colored,(known affectionately as "Barnies" in the Dan Wesson community), and I was told by numerous people that because of the stronger alloy used in some firearms, the bluing salts would make it change to this color.
This IJ 822 has all matching serial #'s, the stampings are all sharp and not worn by polishing. The frame is most noticeable, but the barrel is starting to show the same plum color. In Bill Goforths book on Iver Johnsons, page 79, it states that the barrel, frame, and action were made "extra heavy". IMHO, I think that is the reason that it is turning this color, because of the different alloy used in this particular model.
Has anyone ever experienced this on an Iver Johnson revolver? Your inputs would be most appreciated.
