Piece is round like a skillet but more flat (like something you'd cook a grilled cheese on). There is a raised "8" on the top of the handle, a very pronounced, unnotched inset heat ring on the bottom and gate marked on the bottom in the center. Inside the heat ring it is very pitted, but outside the heat ring is not. It is iron--I did the magnet test. Could this be a piece that was used in a hole of a coal- or wood-burning stove? Thanks for any help.
