Bb Keyed Bugle, ca. 1830-1840. Copper body with brass trim. Nine brass clam shell keys. Telescopic brass tuning slide goes into the lead pipe, which is equipped with adjustment screw. 

The first key bugle patent (5-keys) was by Joseph Halliday in 1811, which he called the Royal Kent bugle in honor of the Duke of Kent.  The keyed bugle was introduced to the United States through Richard Willis, an arranger, composer, performer, who was appointed bandmaster of the United States Military Academy Band at West Point, New York.
