BRESLMAIR silver-plated trombone/baritone/euphonium mouthpiece. - Brand: BRESLMAIR - Silver-plated finish Stamped with "1". Used on a Cerveny Kaiser baritone. The shank is for a medium-thin bore. There is some clouding, but there are no areas where the silver plating is peeling, and there are no major scratches or dents. The shank is also not warped. I measured the size with calipers, but please take it as a reference. Please understand that this is a used item. Thank you for looking.
