I've twice had this title in its 1954 incarnation, but here we have a MUCH more handsome one from 1938. The booklet measures 6"x9" and was owned originally by Service Tool & Supply Co. of Akron, Canton and Youngstown,Ohio as indicated by yellow sticker to back cover. It's clean as a whistle and has 62 pages of facts, photographs and drawings. This is not solely about advertising -- it's a helpful technical manual made easy to read.
