I have no idea where I got this, but for some reason i have ane xtra bell lying around my house, Its a plastic Vito Bell and it fits Buffet clarinets, E11 and R-13 and Festival. (that i know of)

I dont know what to do with this, i dont wanna throw it away, and Its useless just sitting on my shelf,

Um, anybody want it?
all i would ask is shipping charges.

Your local woodwind repairer might like it for his spares box.

...... or sell it on E bay

I doubt it would sell for more than the shipping...LOL but thats a good idea about the spair box

You might be surprised at the cost of replacement parts & also how difficult it can be to obtain them even for current models from reputable, mainstream makers.
