They opened up a new museum in Bethlehem PA a few weeks ago called the National Museum of Industrial History. I posted a thread under the Blacksmith section about a steam powered hammer that is on display. Another unusual display is from the 1876 tool exposition that was Philadelphia, it is from the Nicholson File Company. The display is about 6 ft by 8 ft long, supposedly it displays all the different files produced by them at that time. Across the top lettered in files is "Patented Increment Cut"
www.nmih.org is their web site
Stop by if you are in the area it will be an interesting few hours seeing treadle powered machines, line shaft powered machines, steel industry displays as well as silk mill displays.
