11585	Mellophone	Conn	6E	162839	1918	Eb-C
The 1918 Conn Catalog describes the 6E as an alternative to the French horn in modern bands, but were not appropriate for orchestra settings. The catalog pointed out that bands use French horn music in Eb (which was a short lived convention of the time). The instrument was pitched in Eb and also came with a crook to lower it to C so it could play off of piano music.
