Price reduced! (This is the final price reduction. I don't intend to lower it any further.) The cup is shallow, so I used it for an F tuba during my student days. I think it's a rare model. Cleaning has been done, but it is a used item, so please understand that it is non-refundable and non-returnable. There is a very small dent on the shank. The following is a quote from the manufacturer: ----------------------------------------------------- "Miraphone," founded in Germany in 1946 by 13 craftsmen, is world-renowned for brass instruments, especially tubas. It's a long-selling mouthpiece with a bright, rich sound that extends well. Cup diameter: 33.0mm Bore diameter: 8.2mm Cup depth: Shallow (37.9mm)
