Very good condition, early vintage Santy Runyon Tenor mouthpiece with metal shank ring in a #2 facing. The tip lost a small piece at one point, but someone repaired it well. Bite area has a mouthpiece patch so it is likely in good condition also.
Santy Runyon was one of the great saxophonists of his day and lived well into his 90’s. He manufactured a large number of mouthpieces that people still play today.
