Detail of the heel profile at the place the neck is joined to the banjo pot. This neck was repaired and somewhat altered (by request) to better accomodate the flange and to improve the fit to the banjo pot by luthier John Boulding of Mt. Airy, NC. This banjo is thought to be a 1930s era Slingerland. The Slingerland Musical Instrument Mfg. Co. was based in Chicago, Illinois and was owned and operated by H.H. Slingerland. The company changed names several times, including The Slingerland Banjo Company, Slingerland Banjo and Drum Company and others.
