I would refer to your skillet as a turn of the century skillet. A rough estimate of the date of manufacture could be 1890-1910. If you look on ebay, many sellers call skillets with these markings Blacklock skillets. But no one in the collecting world has definitive proof of what a Blacklock (a.k.a. early Lodge) skillet looked like. It is only postulated at this point. But don’t let that distract from the fact that it is a nice skillet, and an old one at that. There are many old pieces of essentially unmarked cast iron cookware that are next to impossible to identify as belonging to a specific foundry. But the molder marks (Initials) on the bottom of your skillet are consistent with early Lodge markings.
Post some more photos once you have this one cleaned up.
