When I took over this magazine in 2001, we ran a department called Iron Works that highlighted a piece of historical construction equipment. Each month, senior editor Lynn Landberg tracked down a machine and a photo, then wrote a brief description of the machine.
We had been doing this for years, and when Lynn retired we brought in Keith Haddock, arguably one of the industry's most recognized writer of equipment-related books. Keith did Iron Works for us until we retired the department in the late 2000s.
