In 1981, 7 semis arrived with a donated Wheelock Engine that took a year to assemble. Two large boilers were purchased to make the steam required to power the big 110-ton engine whose spokes each weigh about 10,000 lbs. Later a roof was built over it followed by a complete building. Inside is a large display of toy farm machinery and special antique collections. Old tractor and other machinery manuals are sold here as well as many varieties of toy implements by vendors.
