Here's another very rare mouthpiece. This is an original Brilhart Tonalin Streamline series mouthpiece for the alto sax, serial number 164546. Many people know this as the “Charlie Parker mouthpiece”, the same model made famous by him. This one is an original 5*, with tip measuring .071”. The mouthpiece has some light ligature marks around its body, and faint marks on the original black bite plate, but no significant wear to speak of. The black stamping is crisp with no fading, and the original tip and rails are perfect. A truly great mouthpiece for players and collectors alike.
