Gibson TB-1 #9477-18
When style 1 made the transition from the earlier "bracket-shoe" design to the one-piece flange circa 1929, some examples were made with the new rim construction while retaining most of the cosmetic appointments of the earlier 1920s design. #9477-18 (see Gibson banjo serial numbers vs. factory order numbers) is one of these transitional models. The rosewood fingerboard is inlaid with simple dot position markers and the old-style "The Gibson" peghead logo is silkscreened. The dark-finished maple resonator is bound on the back edge only. The tailpiece is the type referred to in prewar Gibson catalogs as the "Grover first model" and the rim label is the smaller "The Gibson" type used on the non-Mastertone models.
