This is a real rare find - a late 40's Zimberoff Hollywood mouthpiece for the tenor sax, serial number 157. This piece was made by Dukoff and represents one of the very early Dukoff metal mouthpieces produced. This piece is all original, stamped a 4 and measuring about .080". While a bit on the smaller side, it does have a lot of room at the tip and can certainly be opened later if you so desire. We are leaving it original because of the uniqueness of the mouthpiece. The piece has some light finish wear but is mostly clean, and has just a single light indentation near the front of the bite plate.
