Original electrical trade vintage catalog for ILSCO COPPER TUBE & PRODUCTS, INC. was located in Mariemont, Cincinnati, OH. Manufacturers of electric connectors, soldering lugs, fuse clips and neutral bars are shown. Seamless copper tubes are drawn down to desired sizes in our own tube mill to insure uniformity in quality and sizes, economy in use and cost and to guarantee dependability. Disbound from a large 1948 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.
