I hope I'm not guilty of Threadjacking here (I apologize if I am), but since this thread deals in part with equipment carrying rather uncommon manufacturer names, has anyone ever heard of electrical equipment by the name of "Mongerson's Machine Works"? I saw a nicely preserved 60 amp 3 pole safety switch bearing this name, back stage in a local high school auditorium. I know very little about it, other than the fuses (ordinary cartridge, non-rejection-type) slide into place and are held there with screw clamps, and the actual switch jaws are not visible, being hidden beneath the entire assembly inside the can (not such a great idea, huh...).
