It is my understanding there were truly around 1800-2000 Marylin's produced out of 7000+ total production. (Not the 200 FUD figure to CYA provided by Wms). Most if not all early production Marilyn's were already distributed in North America before the estate snafu, while many of the later on the line Lola's were mostly exports. If you poke around the IPDB registrations you can get a pretty good idea of what went on. The other thing that slightly skews the domestic Marilyn count are the repro playfields. I happen to have a Marilyn proto with a few unique differences, a few different playfield plastics, boards and roms.
