Prototype for Walthers "Valley Cement" ?

Anybody know if there is a particular prototype structure or plant for Walther’s Valley Cement? I’m about to start building this kit, and want to try to model is like a prototype.

I found an abandoned concrete facility in Savannah, GA this past weekend, right near the big Hwy 17 bridge, and it looks VERY similar to Walther’s Medusa Cement plant, which I’m also modelling. There’s another plant across the river and up about a mile or so, but it looks alot different than Valley Cement or Medusa Cement.

I don’t want to be perfect, but it’s nice to have a direction to go in when you’re trying to make things look realistic.

Supposedly Walthers bases a lot of their buildings on stuff around Milwaukee and Colorado so I’d say there would be a good place to look.
