This from Brian Murphy:

I came across this old Mack C series engine in a storage yard near I-55 just outside of Plainfield. I have no idea where it came from, but a guess is it may have been from one of the steel mills in NW Indiana or perhaps a chemical plant or refinery around Joliet.  What thinks all of you????
