Giovan Battista Cazzani (b. Lodi 1846; d. 1920) was at first a watchmaker, then maker of saxophones. In 1912 Egidio Rampone, who in 1916 married Cazzani's daughter, became a partner and from then onwards they traded as Rampone & Cazzani, although reportedly the merger did not occur until after Cazzani's death in 1920.

A post US Civil War vintage over-the-shouder (OTS) valve trombone made by B. Cazzani & Co of Milano Italy was "likely imported after the end of the war by T. Pirone, New York." [See Phil's Old and Odd Brass]

Note: This horn is very similar to the Cerveny model CAH 501m "EEb-Alto Horn" (see below). It is distinguished from the similar "mellophone" design by the small mouthpipe receiver which accepts a standard size French horn mouthpiece and by the use of rotary valves instead of Périnet piston valves. The accompanying mouthpiece, however, has a very wide 6.3 mm rim with an embouchure-swallowing 18.6 mm inside diameter.
