Silky trumpet mouthpiece, old type, size 15, GP finish. The GP was applied over 10 years ago at a famous workshop in Hamamatsu. Since it hasn't been used much, the GP is in good condition. There are some scratches from use, but no noticeable damage or dirt. This old type is rarely seen anymore, and it's unlikely you'll find one in this condition anywhere else. If you're looking for one, don't miss this opportunity.
