Original industrial trade vintage catalog for GAS APPLIANCE COMPANY, INC. was located at 50 Church Street, New York City, NY. Manufacturers of temperature control systems. Thermostatic valves, quick acting diaphragm, oven and fluid control equipment diagrams are shown. 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.
