I have an original schematics booklet for Williams WPC games.
This one was from either an Indy 500 or a Who Dunnit, don't remember.
I will have this with me at Pintastic, and I have no need for it.
$25 cash: I will hand deliver: Cash only (seemed like a fair price - feel free to shout insults if not).
PM me here if interested, thks.
