Beside this upper PF rollover switch are what look like flippers. They are screwed down and don't move. The actual flippers are beside these flipper look alikes. My question is if these mock flippers were put on to be a conservative/liberal adjustment for this rollover switch between them? I'm not exactly sure where to adjust them. There is a nail right near the tips of the look alikes. I'm guessing I should swing the look alikes towards each other up to those nails. Maybe if swung slightly apart it would be a more conservative setting for the roll over switch. Anyone know or have a better idea?

Thanks for the info Mark. When I finally get the game playable I'm going to set those passive bumpers closer to the nails/pins and see how difficult it is to get the ball in that rollover lane. Then separate them maybe a 1/8" and see if it is any easier to get the ball down the lane. Maybe we've just discovered something!? It's been fun trying to figure out what some engineer was trying to do 75 years ago. But... only a guess.

Thanks for that Dave. The word post is a better description and less confusing than bumper. I'll chalk it up to a brain fart when I originally wrote my question. Makes sense to use something that was available. Like PBPete said, a cost saving idea. What do you think about it being used as conservative/liberal adjustment?

The actual flippers ARE those two posts with a rubber ring. They pivot at the lowermost ends near the center of the playfield. So the left one moves cw while the right one moves ccw. There is a left and right flipper button like normal, BUT there is only one solenoid that actuates both flippers together. Both flipper buttons are in parallel so pushing either button does the same thing... actuate both flippers. The flipper coil doesn't have pick and hold coils like later machines. I haven't operated the machine yet but read somewhere that pushing a flipper button pulses the flippers once. You have to release the button and push it again for another flip. Haven't confirmed this action yet.

DCP, good thing they label the flippers...LOL
