The bulb layout behind the glass is interesting. There's "places" for bulbs, but no bulbs or sockets there. And, with there being two rows (at the bottom), each with 10 locations, one could assume THAT is where the lights for the match feature would be. I'm more of a pinball guy, and in pinball there would be a continuous stepper for the match feature. This bowler has NO stepper like that. There's only three steppers in the back box and they're labeled; Player Unit, Frame Unit and Coin Counter Unit. All three have two coils, one for resetting the stepper. So it would appear, that Keeney manufactured one style of "light board", and just left out the lights and stepper unit for the match feature on the Mainliner. If that's the case, I in fact have the Mainliner and the correct backglass. Good call, thank you.
The reason for my uncertainty is I found on ebay, one being advertised as a Mainliner..and while the BG is the same, the paint is TOTALLY different. The main color is blue, while mine is green...as well as a different design (pics below). I talked to the man selling it today, sent him a bunch of pictures ans he says the "guts" of mine are exactly like his. Really makes me wonder what's up with the two different paint designs.
It came with 2 pucks, different, but both 2-3/16" in diameter (picture below). Weight wise, the solid one is 13.4oz while the one that's hollowed out at the top with the red label is 11.7oz.
The scoring is adjustable (pic of instructions that came with the game below).
Sorry, I don't understand "single game bowler, or multiple game".
Thanks SO much for your input/help. Compared to some of the pinball machines I've gotten, this, doesn't look anywhere near as intricate.
