20 years retired from science teaching, I'm still playing clarinet in our community band. I also have a tenor sax I haven't played for 50 years, and am planning to donate it to some lucky high-school kid. But I would like to know what I'll be giving away in quality and value. Model is "The Buescher Aristocrat." SN is 274679 Low Pitch. Pix attached. Your help and comments will be appreciated.
