C. G. Conn

                                       Conn French Horns
       Just because the list uses 1919 as a starting date, it does NOT mean that 
       some of those products were not produced BEFORE 1919. 
       The C. G. Conn Company began manufacturing instruments in 1874.
       Where there is no year listed in the "Discontinued" Column, the Year of
       Discontinuance may have been unknown, or the model may still have been in
       production in 1965.
