Used Bach 1C trumpet mouthpiece w/ Schmidt backbore. Outside of cup is stamped "1C" and "BB". Shank is stamped S and 25, but we measured the throat at #22. We had it replated at Anderson plating; there are minor imperfections visible underneath the plating but the playing surface is in excellent shape.
