Looks great. I wonder what the cycle of machines on the forum is? How often do leave one State, do a few change overs, and end up near their original home?
Yes it's to bad they don't all come with service log books. I imagine it would be very interesting reading back over your machines former life in arcade/s or pub somewhere. Something tells me that if they did have service books that not many would still have them though and those that did would be missing some detail. Still be cool though.
If they did have log books i'd bet they'd be in mint condition going by how little some operators did to maint their games
