DENIS WICK 4L This is a Denis Wick cornet mouthpiece, size 4L. It was originally gold-plated, but the plating is quite thin now. It has an extremely deep V-cup, but the compact 4 rim makes it easy to articulate. I think it would be useful in serious situations in wind orchestras and orchestras when you want to play softly, or when you want to produce a deep sound in a solo. L ← I think it meant "large fit shank," but it could also be used on Besson cornets (my instrument). Of course, it also fits American-made instruments. I don't see any deep scratches or dents, but please check the photos carefully as it is an old item. Please refrain from purchasing if you are looking for a beautiful item.
