Standard wrench used to tighten the head on a banjo. The head is tightened by adjusting 24 hooks and nuts installed around the rim of the banjo and hooked onto a metal tension band that holds the head in place. Tightening the nuts on the hooks squeezes the tension band and this in turn tightens the banjo head. This banjo was made by the William Lange banjo company sometime between 1925 and 1939. In 1897, Lange and his partner, Rettburg had a banjo company in New York City making a variety of banjos until 1922 when Lange took over and renamed the company Wm L Lange. Due to the success of Lange made instruments, he also began making lower priced instruments for entry level players. At that time, customers desiring their own name on the peghead could contract with Lange to build them and this banjo falls in that category upon the request of Harry Reser. Harry Reser was a famous banjoist and in the 1920s was considered the country's best.
