Original industrial trade vintage catalog for RIDGWAY DYNAMO & ENGINE COMPANY, was located in Ridgway, PA. Manufacturers of products include motor generators, turbo-generator units, AC & DC, steam engines and blowers. Shown are valve gear, section of cylinder and valve, side crank engine, blower and more. Disbound from a large 1916 industrial catalog, this unique old two page technical brochure would display beautifully 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.
