primitive old cast iron pot, rounded bottom hanging kettle witch's cauldron vintage

Rather rough and rusty much used old cast iron kettle, made to hang or stand on a ring - this doesn't sit flat as it is! I couldn't find any makers marks on this one. It measures about 7 1/2" deep and over 11" across the rim at the top.

I love the shape and the bail handle, this looks like a witch's pot. The bottom on this one is so rusty and rough that I can't tell if the lumpiness is a repair, or crude casting original to manufacture. It's in poor condition as it is, in desperate need of a good cleaning and seasoning.
