Nice antique cast iron decorative arched dome top wall heat grate register. The register is in a chipped very lite pale blue finish. There is no breaks, chips or cracks.  It is unmarked, the manufacture is unknown. The louvers are complete and do function as they should.
Overall, it is in good, salvaged condition.  Please look over the pictures and ask any questions if needed. Thanks for looking.
