Otto Link Super Tone Master (STM) gold-plated brass alto sax mouthpiece.
Early Babbitt. The word “Super” in quotes on shank.
7* facing. I measure the tip opening at 0.090″ and the facing length at 20mm. Original, unaltered facing. Easy to see FACTORY MILL MARKS
Excellent condition. Rollover baffle. Rich and flavorful.
HERE are some other really nice mouthpieces I got in at the same time.
