This is an early New York vintage metal Otto Link “Four ****” model mouthpiece for the tenor sax, serial number L41. This piece is table stamped a 4*, and measures .082”. Honestly it is tough to tell if it is original or not. It has a nice thick tip and appears original, but I cannot say with certainty. Most of the original finish has long worn off, but physically the mouthpiece is very straight with no cracks, nicks, or major scratches, including to the black bite plate. A good vintage Link for the player that wants something darker.
