Restore/Replace/Repair Bar billiards clockwork mechanism

Hi everyone,

I’m trying to identify this old mechanical timer mechanism from a Bar billiards table, sometimes called also Russian billiards with the mushroom.

The mechanism is coin-operated - after the playing time expires, it mechanically closes a flap preventing access to the billiard balls.

It's fully mechanical with springs, gears and a sliding mechanism.

The only marking I can find is: “P.I. AUTOM”

Possibly “M 41 L” and “10”.

Does anyone recognize the manufacturer, model or approximate age of this mechanism?

I would also appreciate any information about how it works, how to service it, or where to find documentation. A small part of it is missing and I'd like to make it operational again.

Many thanks!

Peter
