Bob Reeves trumpet mouthpiece, model P10. This is a copy model of a Perantucci 6☆3. The 6☆3 is a model for lead player John Audino, with a rim similar to a Bach 3C and a shallow cup similar to a Bach F. It has a black ruthenium plating finish. This is a one-piece model, which is no longer made. The shank is likely a #4, as there is no specific marking. There are no scratches or dents that would affect playing.
