Gibson TB-3 Mastertone #9549-73, the "Floyd Jacobs"
Style 3, the least expensive model in Gibson's prewar Mastertone line, was revamped in 1929. The model's straight-grained maple changed to mahogany, two concentric rings of white/black/white purfling were added to the back of the resonator, the brass tube-and-plate flange was replaced by a one-piece cast metal flange, and the headstock shape and inlay patterns also changed. #9549-73 (see Gibson banjo serial numbers vs. factory order numbers) dates to the following year and remains in fully original condition.
The longtime (and possibly original) owner
of #9549-73 was Floyd Jacobs (1906--1986) of Mount Vernon, Ohio.
