Rare cast iron bean pot

An awesome piece of history, love it when there isn't a question about the date. Although I haven't been able to find out much else about Greer and King. Very unique how it has the drip ring, also the fact for its age not having gate marks. Found it on Ebay and picked it up for a good price. From what I understand until I bought it it probably hadn't been farther than about an hour from where it was cast.
