This is a beautiful Selmer Soloist tenor sax mouthpiece with the long scroll shank and horseshoe chamber. This is the piece that was issued with the early 50's vintage Selmer Mark VI tenors.
This piece is in excellent condition. It has all of its original gold lettering intact. It has never been worked on, and the table, rails and tip are perfect.
In our experience, these can make very good classical tenor mouthpieces. Or if you prefer a closer setup, can be ideal for small group jazz a la Joe Henderson.
