Original electrical trade vintage catalog for COLLYER INSULATED WIRE COMPANY, INC. was located in Pawtucket, RH. Manufacturers of Resistol cables and wires, used shipboard in Navy and the Maritime Commission, and aircraft for Army and Navy. Superflexible synthetic rubber sheathed welding and locomotive gathering cables are listed. Disbound from a large 1944 architect construction materials book, this unique old two page technical specifications brochure would display wonderfully matted and framed. A marvelous addition to your retro electrical equipment library. Pages are loose and contains a small amount of residual glue on edge.
