Starting in 1930, C. G. Conn Ltd. began production of a cornet that would create a legacy lasting all the way up to 2007: the "Director".The specific design being patented later in 1931, the Conn "Director" 26A cornet, was produced to satisfy a demand for a classic-sounding cornet. This cornet was originally a professional model before World War II, but the "Director" horns made in the 1950s all the way up to the last "Director" trumpets available from Conn-Selmer in 2007 were student models. Beginning in 1960, the Director model was updated to create the 15A with brass bell; this model was kept until 1971.
