I am currently looking for a clear/transparent Buffet B12 clarinet with either gold or silver keys. I know that there were only about 1,000 of them made from what I have been reading. I managed to find one on the internet but it wasn't for sale. Anyone know of a website, place, or person, I can contact to possibly purchase one?

Your best bet is to keep an eye on Ebay. If I'm not mistaken, they were labeled as E11's, but were actually just B12's. They are quite rare and will cost a bundle. Not really worth it in my opinion, but if you are insistent on wanting one, that is probably the place you will find it. Expect to pay a pretty penny.

Here's one for you you on E-bay in U. Do a search for item # 180350807148.
