Back in the 50's Fairbury was a railroad division town & would have had that kind of expertise, although I suspect the tools were actually made by contract elsewhere. If so it would not have taken much space to run an office and have a store room of inventory.
If the Fairbury Public Library kept old City Directories & phone books there might be some information to be gleaned that way. But don't hold too much hope. Lots of small town libraries ignored local history for decades.
