VINCENT BACH CORP. Vincent Bach Mouthpiece 2-1/2C No original box This is a trumpet mouthpiece. I remember purchasing it around 1980. I used it for only a short time and then stored it, so I think it's in good condition. (There is a faint circular scratch on the lower part of the outer surface of the cup.) It might be just right for those looking for a slightly smaller rim size than a 1-1/2C. For reference, I've included a picture of the Nonaka Boeki catalog from when I bought it in the last image. Note: This catalog is not included with the product.
