By looking at my 32-40 in comparison. Sorry having to say: Your front and rear sights look to have been replaced. Otherwise the appearance of your rifle is indeed very nice for its age. If the bore is dark (rusty looking) your rifle will indeed loose some value. But keep in mind your rifle indeed has value being a 100 plus years old and its a true blue Winchester too boot. Out of curiosity. Please come back and let us know what your appraiser has to say about your rifle. I for one would appreciate that effort Sir.
#7 thread is spot on with his info. (As it would be in your best interest to consider re-reading his thread.)
