OK, here's the 1926 reference.
" The first mystery company is the
Craftsman Tool Company of Champaign, IL. This company is listed in Franklin's Directory from 1924 through 1926. Now there is a
Cushman Company listed in 1923, also in Champaign, but that is probably a misprint or the company was bought by or merged with the Craftsman Company. There are no instances where companies are known to produce shoes for just one year. There are no Craftsman shoes found by this company's brand name, although there are many shoes bearing the name Craftsman. They were actually made by the
Marion Tool Corporation of Marion, Indiana. The Indiana company is first listed in 1936. The 10-year gap makes it rather unlikely there is any correlation between the two companies. Marion Tool produced three models through the 1930s and 1940s: a plain bookless model, then-first hooked model had very small blunt hooks, and the supreme design, the
Craftsman Ace is rare in its own right, for only one set is known in collection. The Craftsman shoes have no relationship with the Sears & Roebuck Company, although the catalog did sell pitching shoes for decades. "

So there you have Craftsman Tools disappearing in 1926. They were in receivership in 1922 according to the Papawswrench site. Then Sears brings out their Craftsman brand in 1927.
