CONN 7 Cornet Mouthpiece (for short cornet) It has a used feel and is slightly thin, but it's pink gold. The size is about 16mm inner diameter, and the cup is UV and deep. It was obtained used, so there are signs of use and scratches, but I think it's in pretty good condition. I used it with a BESSON cornet, so I've uploaded reference images. Please check the images. Price includes shipping. Please refrain from price negotiations.
