This is a New York vintage Hard Rubber Otto Link Slant Signature Tone Edge Soprano Sax mouthpiece. This mouthpiece was refaced sometime in the past. Whoever did the work did a great job seeing as the piece looks and plays awesome. The refacer opened the piece up from a 7 to an 8. They also stamped the side of the mouthpiece with 8 for the new facing. The mouthpiece plays with a nice dark, focussed sound.
