DescriptionBrass, German silver, two independent mirror-imaged double-loop sets of tubing, one with a narrow trombone-like bore and bell, the other with a wide euphonium-like bore and bell, both bells pointing upward and forward, separate tuning slides after valve section (cylindrical and conical, respectively), fixed shared leadpipe, four rotary valves (1, ½, 1½, and switch from one instrument to the other), three-point-wing device, one stop pin, clock-spring return.

Schediva developed a number of duplex instruments in the 1880s. In 1901, this experimentation culminated in the creation of a whole family of instruments with both cylindrical and conical bore tubing, which he named "Schediphones," after himself. These included a 4½-foot B-flat cornet/trumpet, a 6-foot F or 6½-foot E-flat alto horn/alto trombone, and an 8-foot C or 9-foot B-flat tenor horn/tenor trombone. This instrument is an example of the latter.
