To wrap up our tractor show posts, here are some stereographs taken by the Keystone View Company of Fordson tractor production in Detroit in the late 1920s. In addition to a shot of finished tractors coming off the assembly line, the Keystone archive also has images of tractor engine blocks being cast, including making the sand molds, pouring the molten iron and the finished engine blocks.
The stereographs are in the collection of the Keystone Mast Archive of the University of California at Riverside.
