OK, here is the answer.
Still not sure who get's the free chip though.

They were used in this game known as Golden Ten, a works man roulette it was also called.
The principal is the same as the roulette but here the cylinder doesn’t spin and there are no objects blocking the ball.
All is static but the ball that turns on a big iron kettle.
Used illegally as a kind of “game of skill” for more than a decade in the Netherlands.
Notice the jetons, I still must list these.
Yesterday casino Nispen (Netherlands) was added on the chipguide.
The balls are from there.

Jo from Belgium.
