So bossninja's first pin could have been ex Abe Saffron??
My Aquarius is a 1970s machine. Up until the late 70s, Luna Park had its own machines and mechanics looking after them. In the back of my Aquarius is a record of who (on the Luna Park staff) worked on it. Saffron's "Arcadia Amusements" began moving in in the late 70s. Saffron also had pins, video games and cigarette machines all around Sydney. Cash from machines was a great way to launder money and dodge tax. There is strong suspicion that Saffron wanted Luna Park - I'm not surprised if he was linked to the fire.
I think the "old" machines (pre 1975) at the auction were the original Luna Park ones.
I loved the old Luna Park and the Penny Arcade. I got to wander around the park before the auction - very errie. Somewhere on the AP site I posted photos I took, including one of the ruins of the Ghost Train after the fire.
