Nice antique cast iron arch top wall heat grate with a nice decorative pattern. It’s in a rust finish. There is no breaks, chips or cracks. The manufacture is unknown as its un marked. The louvers function as they should.
Overall, it is in good salvaged condition.  Please look over the pictures and ask any questions if needed. Thanks for your interest!
