My immediate reaction as well was that the stock and action have been refinished. Just something about the combination that doesn't seem to go together for the gun. But I'm no expert and could very well be wrong. It is a nice gun though.
Part of my reasoning comes from an old English double barrel muzzleloader I bought a few years back. It is in exceptional condition which casused me to believe it had been restored at some point, although I don't know why someone would spend the money on it for a restoration. Anyhow, another area that had me thinking that it had been restored is because the locks have some of the same bright blue that your gun has. I figured someone had attempted a recoloring but maybe I was wrong after looking at your gun.
