Although I read every post on the forums, it is often while engaged in some other activity as well, and with every intention to return to follow up if necessary. I also like to give others time to chime in with what they know first; I know a good bit, but don't wish to be a know it all. Becky's advice is good; many members over time don't pay as much attention to the Introductions posts, and requests for help can get lost in them.
Your skillet has a couple of earmarks most would attribute to Lodge, but Lodge was never known for certain to make a completely smooth bottom regular skillet, toy hammered pieces notwithstanding. I would, given the apparent casting skill shown, attribute this piece to a small unknown foundry, who may have used a Lodge skillet as a model or to create a pattern, modifying it to their specifications.
