Sorry ArchFeyuk, I think that was directed at me.
In which case, it was in Illinois. Stern is located there, so if you were going to go looking for information on the Ito machine, that would be on your itinerary anyway.
Thanks ! My plane arrived late, I'll rent a car to go to Illinois after a power nap. I don't think Hideki's house would be a good lead, so many thing happens inbetween, I'm pretty sure his family doesn't have a clue where the machine could be now (especially if they are constantly moved from a place to another)
