Vintage Battery Operated Toy Mini Pinball Machine Las Vegas Casino Casinoball

Description

This is either 1970's or early 1980's.
The back battery cover is missing.
You can turn the dial and adjust the score manually (111/222/333/etc).
I am not sure what the electronics do.
I inserted some batteries and had to add foil, because they didn't connect tight enough (C batteries).
I was able to get it to light up whenever you hit one of the clear things at the top.
I am not sure if it is supposed to make noise or not, but it does light/flash red (see last pic).
I only used some older batteries too, so it could possibly do more with better batteries as well.
A tiny clear plastic piece broke off somewhere, and it is moving around in the machine.
It's a unique vintage piece!
Please see the pictures.
Thanks for looking!
