Original electrical trade vintage catalog for KILLARK ELECTRIC MANUFACTURING COMPANY, was located at Vandeventer and Easton Avenues, St. Louis, MO. Manufacturers of conduit fittings, including service entrance heads and elbows, bodies, flush switch, explosion proof junction boxes, sealing unions and lighting fixtures are listed. Disbound from a large 1944 electrical construction materials book, this unique old one page technical specifications brochure would display wonderfully matted and framed. A marvelous addition to your retro electric equipment library.
