An Idea.
I was just revisiting this thread and had an idea. You had asked ," it it is a coal distributor, what is the warehouse space for? In Downtown Clarksville Tn we used to have an old style amonia based Ice plant, that was one of the last of it's kind . I went in there once to by a huge amount of ice for a keg party, and the old signs out back said Coal and Ice co. The warehouse side of this building is a little larger than that ice plant was.
