Williams was more in the industrial end of the tool world. Was recently bought out by Snap-on. I have Williams wrenches back to WWI, in my 1920s catalogs they have a big ad. J. H. Williams and Son, New York. You will find more Williams wrenches the longer you stay in the old tool world, I even have a near complete set of Williams sockets. Superrench was one of their trade names. They had a flat bar wrench model with a reinforcing bar that is still one of the heavier types I've ever encountered.
