I have a little update on this little gridle. I just talked to my dad and he got it from my g-aunt, who got it from my g-gma, and he was told by the aunt that it belonged to her grandmother, which would make it at least 5 generations in my family, and my g-gma was born ca. 1877, so it is now identified to her mother.
I will give an additional detail, in that the handle is not like any other handle I've seen, and my family owns lots of old passed down cast iron. The handle has a raised 'edge' on the outer edge, and then slants to a 'v' groove, and then has an edge that forms the eye of the handle that mirrors the one on the outer edge. I sure do wish I had a digital camera so i could show this thing off. It is probably the nicest piece of cast iron I've ever seen. ( I ain't braggin, it's just looks like a master blacksmith forged it yesterday and made the cooking surface look like black glass)
