Missing bumper caps can be a real problem. Otherwise, for Genco, there are other unique parts that may be missing. As long as those are present, everything is fixable or replaceable with a modern equivalent.

Lots of fun to be had on a game with passive bumpers and inverted flippers. Don't expect to get rich when you sell it (especially with the wrong legs), but have fun while you've got it.

Building up and collecting at the kickout looks appealing - looks like more than one way to win, and a challenge to build up both bonuses. Looks fun to me...

Make sure those rollover buttons are present and in OK shape.

If the replacement caps are the wrong size, you can replace the bumper bodies as well. Remember that old plastic shrinks, so you may find that even if the PBR cap has the right numbering or lettering, it may not fit as the bumper body has shrunk.
