BTW NiƱo, the stories of your dad's days pioneering coin op in Australia could fill a book...LOVE the Zac Distributor post!
A well know pinball author had the opportunity to document the entire history, but the planets didn't align at his end. Would have been a great story to tell.
There are still heaps of stories that I sometimes post here. There was a Bally Bingo and Billiard table that Dad made on eBay last week. These were most likely sold many years ago - especially the Bingo.
