Denis Wick RW4B Denis Wick Cornet Mouthpiece This is the now-discontinued Roger Webster model, RW3B. I have removed as much discoloration as possible due to aging, but since it was hardly used, it is in very beautiful condition. It works great with YAMAHA cornets. Please check the condition in the photos. (The plating is regular gold plating, not satin.) Type: Cornet Accessories/Parts: Mouthpiece
