Original industrial trade vintage catalog for THE JOHN H. McGOWAN COMPANY, was located in Cincinnati, OH. Manufacturers of power and steam jet pumps, back pressure and condensing valves. Displacement pumps for all uses. Disbound from a large 1916 industrial catalog, this unique old one page technical brochure would display wonderfully matted and framed. A marvelous addition to your retro industrial equipment library. Page is detached and may contain a small amount of residual glue on edge.
