Original electrical trade vintage catalog for W. N. MATTHEWS CORPORATION, was located at 3850 Delor Street, St. Louis, MO. Manufacturers of pole line protective devices. Cutouts, fuswitches, boabs, rural line protective devices, lightning protection, scrulix anchors, connectors, clamps, woodpecker telefault and more are shown. Disbound from a large 1951 electrical construction materials book, this unique old four page technical specifications brochure would display wonderfully matted and framed. A marvelous addition to your retro electric equipment library.
