Gibson RB-3 Mastertone #8205-18
The banjo pictured above is an original five-string RB-3 Mastertone with ball bearing tone ring, dating to 1926 (see Gibson banjo serial numbers vs. factory order numbers). It has been modified with a replacement fingerboard, refinishing of the neck and resonator, removal of the original ball-bearing tone ring and addition of a flathead tone ring. In other respects the banjo conforms to standard catalog specifications for style 3 for this period with maple neck and resonator, two-piece flange, grooved tension hoop with flat hooks, nickel plating, Presto tailpiece, and fiddle-shaped peghead. The original tuners remain, including the friction fifth-string peg.
This instrument was played in the McCormick Brothers bluegrass band and was used by Haskell McCormick during his tenure with Lester Flatt's Nashville Grass in the 1970s.
