Why not copy the Kaspar instead of the Chedeville?
I believe Kaspar mouthpieces can be excellent, but in our quest to manufacture the best mouthpiece possible, we set out to reproduce the greatest rubber ever made. The Chedeville Company has been around for many years and made their best mouthpieces long before Kaspar mouthpieces became popular. Kaspar actually used later vintage Chedeville blanks to craft many of his fine mouthpieces. Upon discovering the secret to the great rubber of the oldest Chedeville mouthpieces, we then set out to design a variety of mouthpiece shapes and styles. We actually offer a Kaspar inspired mouthpiece in the Behn Vintage Collection.
