Here is a very rare Brilhart Tonalin Streamline alto saxophone mouthpiece, the model most closely associated with Charlie Parker.  The mouthpiece has a low (5-digit) serial number and is in nearly perfect condition.  There are no cracks anywhere and the table, tip and rails are nearly perfect.  There is a very slight tooth indentation, but it's very minor.  If you place a mouthpiece patch on the beak, the indentation is unnoticeable.  

This mouthpiece plays extremely well.  It is very easy to project, and the tone is full and sweet from top to bottom.  Truly a magnificent mouthpiece and one that I'm confident will be a favorite of its new owner.
