Serial number 55622 was stamped on February 27, 1934 and cleared final inspection on May 22 that year. It was shipped to Carl Fischer Inc in Boston MA on July 19, 1934.
This is one of the three guitars from the batch of six that were made with gut strings. That does not means the guitar was constructed for gut strings , just that it was set up for gut strings when it was shipped. This guitar was made with the ebony bar neck reinforcement and bar frets, so it was quite easy to adjust the guitar set-up by changing a few frets.
The tuners are clipped plate G-97 machines with seamed butterbean buttons.
