Serial number 57851 was stamped on October 3, 1934 and cleared final inspection on May 7, 1935 (quite a long time in production for the period). At least four of the twenty-five guitars from this batch had dark tops. It was shipped to Rudolph Wurlitzer Co. in St. Louis MO on April 29, 1935. Clearly, enough of the batch was ready for shipment before the whole batch cleared final inspection.
This guitar is from the second batch of 1934 000-28 guitars with the shorter 24.9" scale, steel T-bar neck reinforcement and T-frets.
The tuners are Grover G-98 clipped plate machines with un-seamed butterbean buttons.
