This is a Dillon trumpet mouthpiece, the Roditi Signature model 1 1/2 C. Please refer to the manufacturer's website for details. In my opinion, it's equivalent to a V. Bach 1 1/2C. There are some scratches and dirt from use, but no noticeable scratches or dents. I think this is a rare item that you won't often find online. If you're looking for one, don't miss this opportunity.
