Original condition is in the eye of the beholder.
The late Thad Scott told me all the old English guns were color cased to protect wear to the metal and the engraving....so that coined/polished reciever and blued action plate with blued screws along with the blued top lever is s dead give away the metal was redone.
Well Joe, unfortunately Thad Scott was wrong. Gun furniture was rarely case colored. Parts that were traditionally blacked would be stuff like top levers, floor plates, trigger guards, for-end buttons, some pins, etc.
Parts that were hardened would be frames, trigger plates, fore end irons, lock plates (on sidelocks & ornamental).
There are exceptions to the rule though.
