My first game was a Gottlieb OUT OF SIGHT
The history was, the guy I bought it from, said his uncle had an arcade when he closed it he gave a game to each of his kids and nephews.
I don't know what happened to the rest of them. But I got a working game that need cleaning and a ring kit.

A freind who I flew R/C airplanes with said he had an old wood rail pinball in his basement not used for many years .
I am sure it needed to be repaired or at least shopped.

I wonder how many games are out there in the corner of a basement or garage.

the backglass survived winters in a Michigan garage amazing.

There are a lot people who have games that are not on Pinside or other pinball forums.

More Examples: My neighbor has a Flash that will need work and its at his other house.
My former employer has a Last Action Hero. I ordered a ring kit for him and told him to replace the 3 AA batteries.
