Re: Conn Saxophone
What you have there is a Conn "Director" model, often nick named "Shooting Star" due to the engraving pattern.
This one was made around 1958/1959, and although very much a student grade horn, this vintage is better than later ones.
I wouldn't pay more than a few hundred dollars for it, in fine, playable condition with good pads. It if needs a lot of work such as a complete repad, I'd limit the value to below $250.00.
