A major contribution to the range of knowledge available to tool collectors, Milt Bacheller’s definitive study of the makers of American patented and manufactured marking gages contains historical and product information on hundreds of known makers of marking gauges. In addition, the book documents all known marking gage patents–more than 350 in all–and reproduces the original patent drawings. A listing of each of the individual patent dates is helpful for collectors seeking to identify a gage. Thoroughly illustrated with superb color and black & white photographs, American Marking Gages has been produced with the same attention to detail and quality as Roger Smith’s classic books on patented planes. If you are interested in tools, you will be absolutely delighted with this new book. Highly recommended.
