Here's an original metal Berg Larsen bari sax mouthpiece. It dates back to the 60's or so, has the bullet chamber, and is stamped a 120/0 M. It measures right at .120". The piece is in excellent condition with only very mild finish wear on the table and no other real wear of note. The original tip, rails, and table are all in great shape with no nicks. It still has its original ligature and cap.
