Original industrial trade vintage catalog for THE M. SMOLENSKY MANUFACTURING COMPANY. Main office and factory was located at 932 Garfield Building, Cleveland, OH. Manufacturers of rotary, check and suction valves. Information on standard, screwed, heavy flange check, noiseless and air line valves. Includes a testimonial from R. C. Bahr. Disbound from a large 1916 industrial catalog, this unique old two page technical specifications 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.
