My 1946 99 is not tapped for a scope. Should I decide to have that done, what would it do to its value? Happy Trails
Drilling holes would drop the value by a couple hundred dollars.
What I would do instead is get hold of a member here by the handle of Lightfoot. He can hook you up with a modified scope base that doesn't require drilling any new holes. It uses the two existing tang holes, and the rear sight slot (like the old Stith mounts did). It's sturdy and works well.
