Gibson PB-3 Mastertone #8120-20
The banjo pictured above is a PB-3 with a ball-bearing tone ring and dates from 1925, the first year of Mastertone production. It conforms to standard catalog specifications for the style 3 of the time with maple neck and resonator, single white binding on the fingerboard and and back edge of the resonator, two-piece flange, nickel plating, Presto tailpiece, fiddle-shaped peghead, diamonds and squares inlay, and Brazilian rosewood fingerboard.
Gibson Mastertones from 1925 are readily indentifiable by two features unique to that year: The ball-bearing tone ring has holes on the outside and the Mastertone logo appears on the peghead rather than the fingerboard.
