This is a vintage Geoff Lawton 7 Star B metal mouthpiece for tenor. The Lawton mouthpiece was originally stamped a 6 Star but was more recently opened by mouthpiece tech Erik Greiffenhagen. It now measures .100”. It plays with a medium warm sound and plenty of power and projection. A great player if you are looking to get a highly present sound and projection with out becoming obnoxiously bright. This mouthpiece is in extremely nice condition as is the facing profile. The table, side rails and tip all look outstanding.
