This is a Florida vintage metal Otto Link Super Tone Master mouthpiece for the tenor sax, serial number N65. This is “double line” Link, from the early days of the Florida pieces. This piece is stamped an 8*, appears to have been double stamped as seen in the photos, but whether this was done at the factory or later is a nothing but a guess. Really hard to say if the facing is original or reworked. My gut says no, but it looks really good! The tip measures .112”. The bite plate is in great shape and the mouthpiece shows typical finish wear as to be expected.
