Yamaha YAS 23 Alto Saxophone.  I'm not sure of it's age.  The body seems to be in good used condition.  The pads look to be in good condition but I'm not a player so take that for what it's worth.  This came from an thrift store. It is tarnished here and there with what I would call minor scratches.  The neck is missing the Octave Pin.  There is no cork on the neck.  It does not have a case.  The serial number is 092164.
