it is possible that Mack made an error on the letting of the rig? the mill at West Mifflin, when opened in 1938 was called the Irvin Works of the Carnegie-Illinois Steel Corp(as the rig is lettered on the hood). Carnegie-Illinois was a subsidiary company of US Steel. I would think they opened the plant with a brand new rig.
Irvin works are in west mifflin (founded in 37?). They had the B models but i dont think they had any fire equipment prior to that. Irwin works (as the truck is lettered) im not sure where they were at, let alone any carnegie-illinois works were.
