Yeah that's true, I think people who buy vintage coin-op stuff have to expect that the thing is not going to operate perfectly 100% of the time. I think somebody else in this forum said that pinball machines will eventually end up in the hands of restorer collectors, just like classic cars.

It's funny because when I'm shooting weddings I like to have a chat with the guys who drive the classic hire cars and their hands always look like they've just done an oil change
