Gibson PB-3 Mastertone #8057-12
The banjo pictured above is a PB-3 with a ball-bearing tone ring and dates from 1925, the first year of Mastertone production (see Gibson banjo serial numbers vs. factory order numbers). 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.
