Conn-o-sax

An unusual variant of the saxophone was the Conn-O-Sax, a straight-conical bore instrument in F (one step above the E♭ alto) with a slightly curved neck and spherical bell. The instrument, which combined a saxophone bore and keys with a bell shaped similar to that of a heckelphone, was intended to imitate the timbre of the English horn and was produced only in 1929 and 1930. The instrument had a key range from low A to high G. Fewer than 100 Conn-O-Saxes are in existence, and they are eagerly sought by collectors.
