Steve,
This is definitely a labor of love. Your skillset is amazing - you were destined to be the person to bring this game back to life.
Your small world story is nothing short of amazing, to put back together the two primary parts of this game, much less from two distant locations. It reminds me of a news article I read in the Detroit Free Press back in the mid 1980's where a guy had his car stolen in Detriot. When they found it days later it was missing, among other things, the front clip (hood, fenders, and front grille and bumper). So the body shop repairing it, as they are accumulating the missing parts, found a used front clip from a parts yard in Toledo, OH, about an hour away. The clip is the same paint color as the original car, and has a scratch on one fender that matches the scratch that remained on the adjacent door. It was the same parts that were chopped from his car.
I've seen the results of the uneducated/misguided in terms of getting a head separated from a body. Saw a Gottlieb Big Brave at Pinball Expo back around 2000 where the same had been done to separate them. It's more common than you think.
Good luck with the remaining work but I don't think luck has anything to do with it now.
