I have the very same one. Condition of mine is not quite as good. Sears bought the Craftsman name in 1927 from the Craftsman Tool Co in Iowa for $500. If I am remembering correctly, The underlined C came after 1932. They phased it out slowly after WWII. I have seen things as late as 1950 with it, but some stuff with the =Craftsman= in the same catalog. Probably they let forging tools wear out before making the change. The 1927-1932 logo has the word Craftsman in a kind of a wave.
