I'm looking to purchase a new mouthpiece, Vincent Bach 17c for use with my soprano cornet. Where on earth can I find one? I have tried the local places (one ordered one for me 5 weeks ago... no reply as of yet ) and none of the other places I have tried seem to have this model. I assume it is a fairly common mouthpiece to find? Can anyone advise? there is bound to be somewhere on the net that sells them! Google hasn't found any for me.
