Well Dwayne, man you have got something, a wife that brings you home cast iron, wow. How you trade her to some cast iron? If it was me, I wouldn't care what kind it was, I'd rave about it.
While I don't know the name of the maker, it looks old, pre 1900 easily I'd say, as you may or may not know, its the kind that sits over a number 8 eye of a wood or coal cook stove, and you flip it over and it turns down in the eye of the stove and comes back up when you turn it to cook the other side. I'd say it has gate marks on it somewhere as well. I see them around every now and then and I have a couple of them. And for 10.00, I'd say she done very well, and you can tell her I said so. ;) Can you clean it up and let us see it again? :)
