Original industrial trade vintage catalog for THE LUDLOW VALVE MANUFACTURING COMPANY, was located in Troy, NY. Manufacturers of valves, for steam, water, gas or oil, manufactured of iron, bronze and steel. Includes detailed information on double-gate, horizontal swing check, vertical check automatic globe air valves and slide gate fire hydrant, list No. 75 and 80. Disbound from a large 1916 industrial catalog, this unique old five page technical specifications brochure would display wonderfully matted and framed. A marvelous addition to your retro industrial valve equipment library. Pages are detached and may contain a small amount of residual glue on edge.
