Keystone Stove Foundry, Spring City, PA

I have been looking all over the internet for information on this stove. It was given to me by one of my customers that was going to put it at the curb. It was an interesting peice and has all the parts and accesories.

The only markings are as follows

Does anyone have information about the company or the stoves? It seems the company was in business around 1902.
