This is a Schilke mouthpiece for a small shank! It shows signs of use, but it's still fully functional and can be used at the highest level. I think the tarnish on the silver can be removed with polishing. I used to favor this series, and this is the one I took the best care of because it was so easy to use. The sound doesn't spread too much and is compact, so it's good for microphones. Please give it a try♪
