This is a Giardinelli 6D mouthpiece for a small-bore trombone. This mouthpiece can also be used on a small-bore euphonium. It is a one-piece design. The engraving is not from the very early period, nor is it the latest small font, but rather the so-called old engraving. The manufacturer's name is engraved as "GIARDINELLI". There are small dents and scratches on the shank, etc., but there are no noticeable stains or scratches, and I think it is in good condition. Please check the photos for details.
