Show on my wood burner for display but it does not fit it  properly. This is a Georgian/ early Victorian cast iron trivet, has a forged steel with hand made rivet PART see photos please. I show it with a measure the widest it opens in photos.  Has some of the original Berlin Black paint finish left, some  rust caused due to age and use, no cracks, good antique condition, would easily clean up with a wire brush and some black lead/grate polish.
