Hi, I have a Jean Marbeau B flat clarinet. I was wondering if anyone could give me anymore info on it. I actually am a brass player and don't know much about woodwinds. I picked the clarinet at a thrift shop to learn how to play it on a whim. It says Jean Marbeau Paris on it. It also says b LP "France" right underneath the barrel. It has a wrap around Register key. And it has an extra key underneath the C/G key. It is Wood, I think Rosewood specifically. And It is in good condition! If anyone could give me an info on it I would appreciate it. I am not interested in selling it but am curious as to how much it is worth. Thank you!!!!
