Gibson TB #606-1

This highly unusual tenor banjo is not illustrated in any Gibson catalogs of the period but is virtually identical to the original five-string instrument #617-1.  The wood is flamed maple, with a flat-back resonator rather than the arched back normally used by Gibson.  The head diameter is twelve inches rather than the standard eleven inches of other Mastertone models, and the tone ring is a solid archtop.  The ebony fingerboard is inlaid with split mother-of-pearl blocks, while the double-cut peghead is inlaid in the flying eagle pattern.  The flange is two-piece and all hardware is gold-plated.  The tailpiece is a Grover clamshell.
