Here we have a sweet King Super 20 Silver Sonic Alto Sax. It has a sterling bell. The sax has wear and will likely need a service to be in playing condition. The neck octave key has a bend but I'm sure could be straightened out.
These are highly sought after saxophones. Many like these more than a Selmer Mark VI or Selmer SBA.
Comes with case and 2 mouthpieces. One King and I don't see any markings on the other. The item "King Super 20 Silver Sonic Alto Saxophone" is in sale since Thursday, November 21, 2019.
