I have an Otto Link mouthpiece that I'd like some input on possible current value. The top of the box says: New "Super" Tone Master; Otto Link bell metal saxophone mouthpiece; 2201 Industrial Parkway Elkhart, IN 46516; and "Choice of the world's greatest artists" on the side. It's a #6. I purchased it in probably 1993 or '94. It's in pretty good shape, the ligature is a little tarnished. Just wondering what anyone knows about this. I appreciate any help.
