This A-6 is from late in the career of the talented, trail-blazing R. L. Givens (he died in early 1993). One of the first independent luthiers, at least in modern times, to tackle carved top mandolins, Givens offered at least a half-dozen different f-hole A models during his career, and the A-6 was his last design.  Gorgeous flame-maple back.  Plays great and sounds incredible.  Amazing shape.  Has a strap button added but other than that, it is all original.
