It is a spider skillet, with the d shaped legs gone. Meaning the "skillet" part will not serve as designed, probably altered to use on a stove top. You have a what spider skillet collectors call a "wedded match". Two pieces brought together that fit and function. The "skillet" is a common type, used and copied by many casters.
Now the lid has some identification marks. The bar handle will be either a King Stove and Range. The earlier cast made in Birmingham Alabama. The center of the bottom of the lid will have a KSR intertwined. This is a slightly raised cast mark. All KSR marked lids have gate marks.
The last option is an unmarked "Bar Handle" lid that is a product of the Martin Stove and Range company, Florence, Alabama. The Martin lids have both gate marks and non gate marked lids. The KSR mark is not present. King Stove and Range moved to Florence, Alabama and became Martin Stove and Range.
As a rabid spider skillet collector, the lid has value. Too bad about the skillet.
Add that the KSR lids all have offset lid gate marks to allow the intertwined KSR mark to show. Also I have never seen a KSR skillet with a casters mark. Some of the very early KSR skillets have double gate marks that are thin and low on the 10 - 14 in marked skillets.
