Briegel Method Tools

These rather specific looking tools were found at a local used tool store. I found the Briegel Method name interesting and a little Googling revealed these are tools made by the company as part of their system of attaching fittings to electrical conduit.
 Here is a link to a rather entertaining history of the company, located in Galva, Illinois from 1936 until 1976. The company was sold to the All-Steel Equipment Co. and the operations moved to South Bend, Indiana.
