well.
$100 and 350 miles later I'm an owner of a Gottlieb Jumping Jack! It cane from a little town called Clam Gulch, population ~ 150 people.
Line cable is broken (no plug on the end) and I was told it worked until it broke off. I guess we'll see what I get!
The owner had it in his shop for 5 years before deciding to part with it. He said it was in a bar in WA (or CA, I can't remember now) and that when they decided they didn't want it any more they had a contest one night and whoever got the high score could take it home. His brother won it apparently. Pretty neat little backstory.
For $100 I'm rather pleased
