These are really cool! I love pinball. I find I enjoy the mid-late 80's and early 2000 models the best. Funhouse, BlackKnight, The Comet, Pinbot, The Simpsons, Univesal Monsters, Mars Attacks.... et all.
I once built a paper Black Knight table in 28mm scale for an Arcade building for an RPG game. It wasn't as detailed or as nice as yours though. How big are these?
Keep up the good work. Pinball seems to be a lost art anymore...
