This is a vintage Otto Link "Early Babbitt" Super Tone Master mouthpiece. This tenor piece is still in its orignal 7 facing measuring out at .103". The piece plays with a big open sound, and is a little brighter than most Links. There is some minor scrathing on the piece and a small tooth indention on the bite plate, but the piece still plays great. The original facing work is fantastic, and this piece still shines after nearly 40 years.
