This page is an updated, full valve trombone model number list. It includes models missing from the model number list, those that were added between 1965 and 1969, and corrections to the list where necessary. The choice of 1969 as an end date is due to the fact that Conn was bought by MacMillan in 1969/1970. New models after 1970 are therefore not included. End dates past 1970 are given, when known.
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", bold indicates dates probably incorrect. All trombones are in Bb unless otherwise indicated.
The following list is by no means complete or even correct. If you find an error, or know of a model of trombone that falls into the criteria mentioned above 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).
