How about the solid state Boomerang?
I encourage the pinball community to help me find this game. It is known to be made, and known to exist. Patent documents on IPDB confirm it's existence. As the restorer of the only Solid State Flicker, I am hoping someone will come forward. I'm trying my best to recreate the game, but an original (or photos of) would really put this project into overdrive.
