Willie's U3 STEINER 4.5D PGP mouthpiece for large-bore trombones. This mouthpiece is a model supervised by Peter Steiner (International Soloist). It has a pink gold finish. There are some scratches on the shank from insertion and small areas where the plating has peeled, but otherwise, there are no noticeable scratches or stains, and I think it is in beautiful condition. Please check the photos for details.
