About Me 

I have spent many years researching the railroad history of the region between the Great Lakes & the Pacific Northwest, as well as Agricultural machinery history with emphasis on the Minneapolis-Moline Company, and its predecessors, including the Minneapolis Steel and Machinery Company "Twin City."

Both of these companies well known for farm tractors and machinery, were significant contributors to structural steel work fabricating and building many bridges, buildings, water towers, and other structures from 1902 thru the WWII era. I am slowly trying to document all know machines and structures they built, fabricated and or sold over their corporate life.

Through corporate evolution, they are now heritage companies of AGCO Corp., Duluth, Georgia.
