Hi, I have been contacted by a friend of mine to look at someone's pinball machine. Turns out it is an old Williams Jalopy for the early 50's It is all there but needs some TLC. I was wondering if someone could point me in the right direction as to where to start to say get this thing to start a game or take credits. There is no manual and this is a little older than I am used to tinkering with. ANY help is greatly appreciated. Would love to see this thing in action. THANKS
