Perhaps the earliest Gibson banjo Gryphon has offered, the serial number/Factory Order Number on this beautiful little time machine puts it firmly in 1921 (that number is also listed in "Spann's Guide to Gibson" as a batch of "MB" models). Gibson banjo models were evolving at a breakneck pace during this period, and this early version of what became a popular banjo variant never appeared in a Gibson catalog. It predates the "trap-door" Gibson mandolin banjo models by almost two years and has the hollow shell construction. Gibson's Style numbers for it's banjos were also evolving, but it falls somewhere between Style 3 and Style 4. It's about as original as possible, the only change being a small Phillips-head screw added to stabilize the tailpiece mounting. Along with all original finish and parts (and pearl nut), it still has its original bridge and calfskin head, plus the original hardshell case. And in that case is the case key and the wrench for tightening the head. Excellent condition throughout and quite playable as long as you don't get carried away on the upper frets (where all mandolin banjos are tonally challenged anyway). A great example of early Gibson craftsmanship and in exceptional condition.
