The Stevens Tool Catalog and price list is from about 1923 and has pictures of all the Speed Up tools they made at the time. There is an index by name and part number. If you have a tool and don't know what it is, then you can identify it in the pictures. If you have a name or part number, then you can see what it looked like and what it's purpose was. The Stevens Tools are for Fords, Chevrolet, Chrysler and many other manufactures. It is a fascinating book just to see how the tool manufactures started making tools immediately to speed up repairs and reduce the labor of auto maintenance. Eighty pages of information that you can't find anywhere else.
