This is the extremely rare Martin 5-K Uke from 1928. This is the holy grail of vintage prewar Martin Ukuleles. Figured Koa top, back and sides with Abalone trim on top and back, a gorgeous Pearl Flower Pot inlay adoring the headstock and fancy inlays on the bound fingerboard. The original case for this Soprano 5K Martin Uke is in excellent condition, as is the entire instrument. Truly a museum quality piece that has been preserved for over 80 years.
