Discoveries, discoveries, discoveries!

So, I was given a few boxes of 'stuff' from an estate auction here in TN, but had no idea what the heck was in them. There were a few piece of obvious 'junk' (not the good kind of junk!), but there were also some kinda interesting things as well. The thing I'm loving right now is this bag (?) from the Markle Lead Works that used to be in St. Louis. 

It's been beat up a bit over the years, & has reddish stains on the side that has what looks like a drawing of the factory, but overall it's kinda interesting. I found a quote about the history of the company & such, but other than that most info about what I've found & how old it probably is just isn't jumping out & hitting me. 

I'm not sure what I'm going to do with this, but it's just too cool to throw away.

"The Markle Lead Works, National Lead Company, and the Hoyt Metal Company were consolidated into the United Lead Company in 1905. This plant covered 30 acres of land and employed 500 men who made lead bullets and pellets for shotgun shells. A wooden "shot" tower 90 feet high was used for making the pellets. At the top of the tower, molten lead was poured through a sieve device which allowed lead particles to splash into a water-filled tank at the bottom of the tower."--Quote from the book Granite City : a pictorial history.
