The Baritone and Euphonium model number pages

R. Jones' Conn model number site doesn't give a baritone and euphonium model number index. This is an attempt to construct one. I have included an extra column to indicate the year(s) when the instrument was (at least) in use. If both the "Year Introduced" and "Year Discontinued" column is filled in, the "Years Used" column is left blank (no need stating the obvious). Italics indicates "educated guess".

The following list is by no means complete or even correct. If you find an error, or have a baritone or euphonium produced before roughly 1970 (see serial number index) with a model number that doesn't appear on this list or is produced outside the years indicated on this list, please let me know (see main page for e-mail).
