Hello, I came across a pre-prefix Ruger No.1 Mod. 1B in 7X57. Wood is quite dark with fancy black streaked grain pattern. Forend checkering pattern different than on recent no.1's., quarter rib, 26" med. wt. brl. Overall gun looks to be near new. Has rings. When I walked up, seller said he could go $1800.00..price marked was $1900.00..I didn't make offer..thought I would check with you guys first. Are these early No. 1 in 7X57 rare? What would be a fair price range? Thanks alot!
