The wear at inserts, the scoop, drops and top of switch where the ramps drop would indicate it has more than 600 plays. I think that it was rom updated before you picked it up, which should of cleared the total plays out. Just FYI, all the wear looks like normal wear on a baywatch. Mine has it and it is a re-import from Germany. But I would agree, the cabinet looks really really nice.
I'm still curious if the stern lollipop rails can be retrofitted to the baywatch/segas
