Excellent vintage hard rubber Frank Kaspar mouthpiece for the Bb clarinet. It is Cicero vintage Kaspar, stamped a # 13, with tip measuring .046” (1.17mm). Its hard rubber body shows oxidation for its age, purely cosmetic, and only very fine ligature scratches right on top of its body. The facing is in like-new condition, and the beak has always been protected by a guard, showing no teeth indentations or wear. Even much of the factory white stamping remains crisp and clear with little fading. A fantastic, highly sought-after mouthpiece for serious players. Does come with a metal ligature and Buffet Paris cap.
