I started a project that involved mapping and documenting significant information onf former Allis-Chalmers factory complexes. Using maining literature and books, as well as help from fellow Allis-Chalmers enthusiasts, I am mapping out the locations of these factories using Google Maps tool. The map is not done yet, but I am working on adding locations. The blue markers are complexes that were part of the large Allis-Chalmers firm. The green markers are locations of industries that built components for Allis-Chalmers under contract.
