Original electrical trade vintage catalog for WM. WURDACK ELECTRIC MANUFACTURING COMPANY, was located at 4444 Clayton Avenue, St. Louis, MO. Manufacturers of dead front distribution panels, circuit breaker, switchboards, meter control panelboards and cabinets, lighting panels, modulite lighting control system, experimental laboratory switchboard and panelboard installations. Disbound from a large 1942 electrical construction materials book, this unique old two page technical brochure would display wonderfully matted and framed. A marvelous addition to your retro electric equipment library. Pages are detached and contain a small amount of residual glue on edge.
