Thank you for viewing. This is a signature model mouthpiece by Ian Bousfield, who has served as principal trombone player at the Vienna State Opera, among other positions. The size is S4, for large bore trombones. Two rubber rings are included. There are no major scratches or dents that would affect performance.
