Hello..........Thirty years ago my Dad, an amateur sax player, passed away. I've had his Conn Alto sax ever since. It's engraved Elkhart Ind. USA. Other markings are 6M and K20156 (probably the serial no.) If I put it up for sale what would be a realistic price? I would estimate it's condition and the cases condition at about a 7 or 8 out of 10. I think it was made around 1966 or 1967.
Thankyou for any help....Dave
