STW, I just bought a pre 64 win 30-30 with swivel slings and not sure if I will keep em, Front swivel is mounted in barrel band and rear in stock. It is in transit so I haven't had it in my hands yet. If interested let me know, as I will just disgard them. Where in Utah you located , maybe we could do some switching. I'm in St. George area. Mine should be 1950-51 production.
