Original industrial trade vintage catalog for HOMESTEAD VALVE MANUFACTURING COMPANY. Main office and factory was located in Pittsburgh, PA. Manufacturers of Straighway, three-way, four-way, angle and locomotive blow-off valves. Charts and diagrams are provided. Disbound from a large 1916 industrial catalog, this unique old two page technical brochure would display wonderfully matted and framed. A marvelous addition to your retro industrial equipment library. Pages are detached and may contain a small amount of residual glue on edge.
