Quoted from lyonsden:In a pin (scattered in the cab and coin box). Didn't know that WULFF was a slot machine. They have/had slots in Germany? WULFF looks like an electronics entertainment company there: https://www.ballywulff.de/ If I recall, I got these from a Baywatch reimport, so something from the mid '90s.
Bally-Wulff is a totally different company. And is not related to Bally(pinball) wich I never understood because they share kind of the same logo. But different story...
Here is a game I used to own.
Seems like your tokens are related to any Fun-Amusement game(wich my game wasn't)
