Congrats Toyguy! The kicker configuration on Ballyhoo is really quite fun! You can keep a ball in play for quite some time, which is unusual for a flipperless game.

You might try calling PBR to see if they have schematics. Unfortunately, with machines that were close to the end of WWII or earlier, information is thin on the ground.

I've played one, and I wish I could remember the person's name that owned it... I'd put you in touch.

Luckily, the internals on a game of this vintage are usually simple enough that you can follow without a schematic.

I'm not sure what the timer is supposed to do in this game.

In older games, it would cut the power, but typically only in battery-operated games. A game made in 1947 should not have a battery option.

The bell pictured is just a cover for the spring inside the mechanical timer. Doubles as a bell housing, but doesn't ring. Some schematics show a baffle or shuttle/shutter switch which might be connected to the timer. I see two sets of switches. Perhaps the timer is supposed to move the slide back and change the switches' state?
