Chicago and Northwestern Railway Blueprint for Gas Electric Motor and Trailer Trucks. Date built 1926, and the builder is The St. Louis Car Company. The car numbers were 9091 through 9903. Blueprints measure approximately 38 1/2 inches long by 27 inches wide. Prints are in very good condition with some chipping and loss of material around the edges some tears. These are full page drawings and detail drawings. Some pages feel very dry and brittle. Drawings all appear to have been submitted by the St. Louis Car Company. There appears to be some revisions that were received 7/9 of 1930 from ECW Rausman for the Gas Electric Motor Cars Truck lot number 6013 card numbers 9901 9902 9903. Blueprints are a great find most could still be framed. Blueprints have been rolled.
