In 1960, both models were updated to create the 15A/B and 17A/B, with brass and Coprion bells, respectively. There also was a Coprion (100% pure copper, formed by electrolysis) version of both produced, the 18A/B. The trumpet counterpart, the 14B (the letter A was used for cornet models, B for trumpet) was introduced as well. In 1954, the basic design and layout of the "Director" was recycled to form a new student cornet, the 14A. The original "Director" 26A (there were no "Director" trumpets, trombones, or French horns yet) was produced from 1930 to 1941, when it was discontinued. Here is a small showcase of the various horns and the impact they made. 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. The trumpets derive their name from a series of stars which are engraved along on the main tube, near the bell.
These were built between the early fifties to 1970. The official description from Conn is listed below: The 'Shooting Star' is the unofficial name of the early Conn Director Trumpets. The specific design being patented later in 1931, the Conn "Director" 26A cornet was produced to satisfy a demand for a classic-sounding cornet. Serial number K55481 dates this trumpet to 1967.
