, by . Pages. . Illustrated with photographs and period engravings. 8 1/2" x 11". Hard cover. This major contribution to tool research by Philip Stanley would be invaluable if it contained only the detailed analysis of the design and function of every rule ever produced by the Stanley Rule & Level Company, which it does. Stanley's book goes much further, however, to include commentary on relative scarcity and value. Stanley's commentary brings life to the seemingly dull subject of tables and scales. Additional chapters detail the rule manufacturing process, the principal competitors of Stanley in the last half of the Nineteenth Century, and reviews some of the specialized patented rule modifications that command great collector interest. The superb photographs illustrate the many features of the Stanley rule line. A book not to be without. $44.44 (BK-0000)
