This is a Yamaha YAS-23 tenor saxophone. Made in Japan. Appears to be in pretty good shape. There is a dent on the bottom (see photo). Finish is good. Does have some aging in spots (see photos). Pads look good. Everything seems to work. How well, I do not know. Please take into consideration I have no way of testing as to how well it plays or the work that may be required. Case is in good shape. Thanks for looking and best of luck!
