I am trying to find out more about the Buescher 400 tenor Sax left to me by my parents. I was thinking of donating it to my high school or learning to play it, but before I make a decision, I would like to know if it's worth repairing/tuning and/or just donating to a school. The markings say "Buescher 400" and it has B11 beneath the serial number.
