SOLVED: This apparently is a baking dish. Thrift store find for my wife. But why is there a hole in the side? What is it?

Oh, and it's LARGE. That's my range it's sitting on, and it covers about 2/3 of it.
The inset ridge at the top makes me think maybe it had a lid at one point? Looks like you could cook a turkey in it, I wonder if it was itself a small electric oven, but now is missing the lid, rack, and heating element? That would explain the hole and the size.
The feet on the bottom really don't seem practical for an oven rack, completely unnecessary if that's what it's for.
