Seeking value of Winchester Mod 70 220 Swift

Purchased Winchester 220 Swift from widow in 1995. Excellent condition with only blemish a pea sized flat blemish on clean and unscratched blue barrel. Stock unmarked w/scope and sling, all like new. Minor bluing missing on Butt Plate. Super clean throughout except that small blemish on barrel. S/N suggests 1957 manufactured year.

I'd say your Winchester made in 1957 should be somewhere in the 1500 range if as clean you say it is..
