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 it's in very clean condition as it was hardly used. It's a great match for YAMAHA cornets. Please check the condition in the photos. (The plating is regular gold plating, not satin.) Type: Cornet Accessories & Parts: Mouthpiece
