Alto sarrusophone

The alto sarrusophone is the alto member of the sarrusophone family of metal double reed instruments. Pitched in E♭, its body is folded only once, and has a bocal that resembles the neck of a tenor saxophone.
Historically it was built in the late 19th and early 20th centuries principally by its inventor, Parisian instrument maker Pierre-Louis Gautrot and his successor,, as well as Evette & Schaeffer and Romeo Orsi of Milan. It is currently only available by custom order, from Orsi or German instrument maker Benedikt Eppelsheim.
