I was lucky enough to visit the Steamship "Arabia" Museum in Kansas City and it really is very good! I'd say that, at least, 70% of the content of the ship is on display and some pretty big bits of the ship herself.
I had to laugh though. In the conservation section there was a guy preserving a wooden block plane. He was treating it with the care and respect you'd expect for an antiquity. Only problem was it was identical to my own block plane that I'd used on a job just before leaving for the holiday.
