This listing is for a vintage (Leblanc) Vito Bb soprano clarinet mouthpiece. It is stamped "FRANCE" on one side, and "2V" on the other. The tip opening measures .042" (1.10mm). It is made of hard rubber, not plastic. 

This mouthpiece is in fair condition. It has some minor nicks on the tip and side rails. It's nothing that would prevent it from playing as is, but it is probably best suited to being a blank for refacing. These are made out of great old hard rubber, so it is perfect for this purpose. Aside from the aforementioned nicks, the facing is smooth. There are also some light nicks on the beak, but no tooth gouges. There are minor scrapes/scuffs on the exterior. The cork is in good condition. It has been cleaned/sanitized.
