Looked a little more closely, there's an 8 on the handle, the Erie is in quotes and nothing else. Same sale, I got a Lodge 4 in 1 lid with the big triangle mark, an unmarked #10 Lodge Dutch oven with 3 notch heat ring, and unmarked #10 Lodge chicken fryer with 3 notch heat ring and lid, along with 2 cast iron register covers (never seen anything like them--they're not the square or rectangular flat ones, they're narrow and 3 dimensional-I'll post pics when I have more time), all for under $20.
Still like to date the Erie though--by the skillet rules, wouldn't this be a series 2? Guess I'll have to post pics--the handle is curved quite nicely.
