This is a Piccolo Trumpet mouthpiece, model 11A5. It's similar to a Schilke 11AX, and I've heard it's easier to play in tune on a piccolo trumpet than the 11A4. I've only tried it a few times. It's in overall good condition, but there are a few minor scratches where it contacts the instrument. The 11A5 is often difficult to get, requiring special order. Don't miss this chance! I'm selling it because my teacher has decided I should use a different mouthpiece.
