It was either 1967 or 1968. My Mom took me along with her to the Rexall Drug store in our small town, in rural Manitoba. In the back was a couple of men (could of been older teens), playing a pinball machine. Asked my Mom, "What is That!" She tried to avert my attention, but to no avail, I was very interested. One time we went there, no other customers were in the store. I got a Dime from her and went over to the pin, stuck the 10 cents into it, then promptly moved an ashtray full of butts off of the little shelf on the game, to a close table. Do remember that the play time was short, but that was it! Flashing lights, bells, and that shiny ball just whipping around all over. Pinball had me, "Hook, Line, and Sinker"
I can't remember the theme, but certainly that shelf was etched into memory. Fast forward to 1982 I was looking for a used EM in Vancouver. Went almost everywhere in Lower Mainland for a game. Saw one with that shelf, and legs that looked like they off of a dinning room table. Took the, 'How Heavy is it Test', it is heavier than most pins, strong and thick plywood construction. Didn't buy it, couldn't remember it's theme either. It was in good condition and most likely I should of bought it, it was less than $400.00.
From the internet somewhere that Williams cabinet is described as having an anti-vandalism design. It was impossible to kick the coin door, or the bottom of the game in the front. With an up swung kick.
