Thank you for viewing. This is an Otto Link Florida era mouthpiece. There is some rust, but the tip rail and other areas are in very clean condition. The facing is likely original. This is a very easy-playing piece. The tip opening is a 6. The small font used to indicate the tip opening is characteristic of the Florida era. I am selling this because the tip opening is too small for me. Please note that this is a used item and no returns or refunds are accepted.
