Williams Strike Zone PInball 1970

Willims 1970 Strike Zone Pinball.

This was my frist EM game..purchasd about 3 years ago for $150. Has a crack in the backglass and some planking in the playfield. It has some unique features including a total of four slingshots..two above the flippers and two on each side on the pin rollovers. Also, the pins on the backglass light up as you go over each of the pin rollover buttons. It needed a minimal amount of work..flipper rebuild..the player unit stepper in the back back was a bit gummed up, the playfield and the plasticks were dirty, one of the pop bumper rings was broken. I replaced all of the old metal coil sleeves with nylon. I wanted to post this because I could not find any videos of this game..also I've find that seeing how they should play might help others out.
