I am planning to attend a few swap meets this weekend to look for some parts to my winter projects. One thing I keep my eye out for is vintage tools. I like them because it is rare to buy an antique that you can still use after you restore it. Some of the vintage drum brake tools are better than the ones you can purchase today. But, sometimes I will see something and ask, “what is it?” Here is a quick identification guide from the June 1941 edition of Brake Service Magazine.
