I have always been told that the russian guns was boiled in oil but as i never have seen any of those guns i don't know.
AS far as I know about dip blue there is some proceses that contians discolored cupper and this can of course be removed.
I don't belive that it will be possible to nickelplate a gun above it's orignal blue as the parts have to be totally cleaned before plating.
I have had a lot of plated guns striped from the plating but they are always greish underneath of the plating.
