Gibson PB-7 Mastertone #E3281-4

Gibson’s 1937 catalog introduced its new line of top-tension Mastertones, which the company hailed as “the alarm clock that is going to wake up new possibilities in banjo playing.”  The least-expensive top-tension model was style 7, seen here in a plectrum configuration.  The pot conforms largely to standard specifications for style 7 with a resonator back carved from two pieces of solid maple, a twenty-hole flathead tone ring, top-tension hardware, and nickel plating; the armrest is a later replacement.  The standard inlay pattern for style 7 Mastertones consisted of bowtie-shaped fingerboard inlays embellished with three slashes in each side, with corresponding peghead inlays.  The “stairstep block” fingerboard inlays seen here were typically used on style 12 and style 18 top-tensions; the fleur-de-lis peghead inlay was not a standard specification on any Mastertone model but is sometimes seen on top-tension models and well as style 75 Mastertones.  The inlay combination seen on #E3281-4 (see Gibson banjo serial numbers vs. factory order numbersseems to have become more common beginning in the early 1940s and was actually depicted in one catalog illustration of the TB-7 in Gibson’s Catalog BB of 1942.

The “Made in U.S.A.” label inside the resonator identifies this as a banjo originally shipped outside the United States; #E3281-4 was sent from the Gibson factory to South African dealer H. Polliack and Co., Ltd., on May 16, 1941 along with its “littermate” #E3281-6.
