This is a genuine mouthpiece for the Conn Constellation, a legendary cornet. It is entirely gold-plated, with a two-tone design featuring silver plating on the shank. It has a bore size similar to a Bach 7C, and a typical U-cup. The rim is somewhat flat with a clear bite. Compared to the situations where the Constellation was originally used, this mouthpiece is more suited for classical music, combo, and wind band settings. This is an old mouthpiece, so it has some age-related scratches, but they do not affect playability, so please rest assured. It is offered at a reasonable price. We hope that those who understand this will purchase it.
