Warburton trombone mouthpiece 12T for small shank. I purchased this item used and kept it in my collection, but I am selling it to organize my belongings. ■ Model: Warburton-USA 12T Small Shank ■ Plating: Silver ■ Condition: Used, but I think it's beautiful with no scratches or dents. There are slight scratches on the shank from insertion into the instrument, but they are not noticeable. ■ There is no original box.
