This is a Denis Wick mouthpiece, supervised by Steven Mead. I stripped the plating myself. Without the plating, the response is good, and it produces a light, airy sound. It has a unique appearance, so it's recommended for those who like a cool, understated look. I'm selling it because I've started using a different mouthpiece. The rim is silver-plated. Cup inner diameter: 26.00 Bore diameter: 7.40
