Nice Old Hard Rubber Mouthpiece by George M. Bundy, Facing 4. This Mouthpiece is in very good shape. The body looks very good and shows just a little oxidation around the shank which is very typical of older hard rubber pieces. There is a very slight bump near the left side of the tip of this piece. The table and the rails are both in very good condition. The tip opening on this piece is right around .073”.
