NMM 6887.  Over-the-shoulder cornet in E-flat by Elbridge G. Wright & Co., Boston, ca. 1860

While Elbridge G. Wright of Boston was best known for his keyed bugles and, in particular, for his fine presentation instruments such as NMM 7059 and NMM 7060, he also experimented with valved brasses in the 1840s. When he entered into the production of string-operated rotary valves, he varied, over time, some of the small details in his design. For example, this instrument shows a rotor stopping device with two pins, while an earlier over-the-shoulder cornet by Wright, NMM 7334, has only one stop pin. Originally an over-the-shoulder cornet, this instrument was converted into a bell-forward cornet at an unknown date. The over-the-shoulder configuration was reconstructed in the late 20th century.
