Having found the original listing,it looks like the engraving has been picked out .Engraving on the barrel lump looks more worn than the rest also.
Nice looking gun though!
I agree with this observation by imperdix. If you look at all of the engraving on the rest of the gun, it appears that the engraving on the areas where the engraving is cut into the blued metal doesn't even match the other engraved parts of this gun. bushveld makes some good points too. A closer look with a loupe would be the best way to confirm things.
