This is a very unique find – an original Dave Guardala Liebman model tenor sax mouthpiece. Looks like serial number 1314, though in typical Guardala fashion, the writing is very faint and hard to make out. This is a true handmade Guardala, and is in excellent condition. The silver plating shows minimal wear, and there is only a single light indentation in the original bite plate. The facing is original, and the tip and rails are pristine. It measures close to a 7 at .098”.
