We have here a 40-hole archtop with a 1-piece flange, neck by Frank Neat with the "flying eagle" pattern inlays, "fat-boy" rim, flamed walnut resonator and walnut stained mahogany neck. All metal parts are gold-plated except for one coordinator rod, most likely not original, though all the parts are, probably. The FON # is 9466-10, and still visible in the resonator under some added gold paint, which Joe Spann puts as a TB-4 from 1929. Condition is near perfect. A killer sounding archtop Mastertone!
