c. 1720—Augsburg, Germany
Christoph Augengicht, Trombonist, a watercolored engraving that is part of a series of musical caricatures by J.A. Müller, shows a trombone with a slide that extends past the bell, but a back bow of tubing that does not quite reach behind the shoulder. The player uses an extension handle on the slide (see below image; public domain) (German National Museum, Nuremberg).
