Trumpet mouthpiece, Jerome Callet's Miles Davis model. I used it in my student days, and it's now a hard-to-find vintage mouthpiece. The V.F. (Friedman) model is said to be very valuable. There are some scratches and dirt from use, but I don't think it will affect playing. (It has been cleaned, but some old dirt remains inside the tube.) Also, please refrain from purchasing if you are sensitive to used items, as it has been stored at home. There is no box, and it will be wrapped in cushioning material and shipped via Yu-Yu Mercari or Raku-Raku Mercari. Please check the photos for the detailed condition of each part.
