What I need now is a Dennis Wick 3,4/5 or equivalent. What I have to exchange is a new Vincent Bach No.6 in silver plate. As I only used this mouthpiece for approx 2 days the rim and cup are mint as is the rest of the piece. (its mint - as new) .... with box and sealed bag (originaly opened not ripped with scissiors) I bought this on the internet in error thinking it to be ideal. Have you a near new Dennis Wick 3,4/5 or equivalent to exchange ? thanks.
