This sort of tool is normally used in sheet metal work.  I don't know the
specific industry this tool was used in, but similar tools are used in
automotive body work for example.  I've also seen similar tools used in
industrial sheet metal work making parts such as flange collars; think HVAC duct
take-offs but larger in the case of this tool.

The source of the tool has no idea, and the only flange bar I have ever run
across is a specialized beam clamp-and-bar for tying off a safety line. Anyone
have knowledge of this tool, its intended use, or the maker?
