Vintage All- Star Silver Mouthpiece. Quoting the January 1959 issue of Conn Chord magazine. The All-Star mouthpieces were made by The Pan American Company, a division of Conn from 1929-1958. The All-Stars were easy to blow being designed to aid the player in achieving a full, easy tone range. The cup had a broad flat rim designed for comfort and help in intonation. The mouthpiece appears yo have a fairly deep cup, I'm guessing close to a Back 3C. It is in excellent condition (See photos.
