Welcome to the club, and I hope you stick around! The Performer was introduced in 1990, so it's an early one for sure. Lots of interest in what we call the SS here. (SS for stainless steel table) Pics are always welcome! Let's see it! There have to be prototypes sitting around here and there, and with a neighbor like that you never know. Was his name Jim?
We try not to discuss values here - it's so subjective. Browse around and you'll see what people are paying, but it's a wide range; from free on up. Better to just clean it up and use it - they are great kettles to cook on.
