This is indeed a real find. It was made during a transitional time for Gibson going from the bow tie style in the late sixties to the two-piece flange style and the different inlay pattern of the seventies. The thing that is unique about this it is an RB 250, but it is not mahogany like the standard rb250 was. This has a maple three piece neck and a coveted Faulkner tone ring with a one-piece flange. . All brand new frets done very recently. I have played this on some shows recently and it is a hoss. Message me if you have any questions at all. $3500 obo.
