K.R. Wilson was the official supplier to Ford dealers for Ford service tools from the 1920's to the 1950's.
Original K.R. Wilson tool catalogs are quite difficult to find, but several are reprinted and are shown below. These include the 1926, 1931, 1936, and 1940 catalogs.
These catalogs are quite valuable to help identify those odd specialty tools found at swap meets, as well as to get good ideas about how to perform various service and repair operations in your own workshop.
