It is my belief that I have a complete set of tools, and they are all in pretty good shape. This one belonged to my mother and came in it's original box. She had two others: a 606 indenter and a 1000 hand vise. They belong to my brothers. These tools were important because a clean, straight cut makes for a great fit between the conduit and fitting - quite useful when you're trying to "fish" wiring through the line without getting hung up. The patent was applied for in 1933 and approved in July of 1935. I have examples from both Galva and Moline.
