Hello. Available is a vintage wood Buescher True Tone Bb low pitch clarinet upper joint. Take a look at the photos. Keywork is fine. Pads are old. There is a hairline crack as pictured. It looks like someone applied some glue at some point. It's hard to see, but may extend under the keywork. Marked Bb. LP. Buescher. True Tone. The serial number of 14487  should place it at about a 1911 going by the charts. Thanks.
