What is the value of a Winchester Sporting Rifle take down cal 45-70 with Lyman sight manufactured in 1897 in very good shape?

The value of these winchester rifles of that age is substantial.As yours is a takedown model that adds even more value to it.I would have your winchester appraised by a winchester collector assoc. member,or a gun collector with a large collection of winchesters to get the true value amount.we could be talking in the thousands of dollars range.
