Original electrical trade vintage catalog for THE OHIO CARBON COMPANY, Main office was located at 12508 Berea Road, Cleveland, OH. Manufacturers of Industrial brushes, Ohiohm resistors and suppressors are shown with details. Grade selections are listed for several motors and generators, and battery chargers. Disbound from a large 1948 electrical construction materials book, this unique old three page technical specifications brochure would display wonderfully matted and framed. A marvelous addition to your retro electric equipment library. Pages are detached and contains a small amount of residual glue on edge.
