In 1937, Gibson completely overhauled its Mastertone line. The top-tension styles 7, 12, and 18 were introduced, style 3 was renamed style 75 with its price lowered from $100 to $75, and all other Mastertone styles were discontinued. This banjo is from the last known batch of prewar Granadas. It conforms to standard catalog specifications for a thirties Granada tenor with curly maple neck, curly maple resonator with sunburst finish, a one-piece flange, gold plating on all hardware and engraving on the tension hoop and armrest, a forty-hole archtop tone ring, flying eagle inlays in a rosewood fingerboard, a double-cut peghead, multi-ply black and white binding on neck and resonator, and a clamshell tailpiece. The tuners are high-end Grovers with amber buttons.
