3 Antique Round Ornate Grate Cast Iron Floor/Ceiling Heat Registers 10 Inch

Three 10 inch antique adjustable swivel floor and three antique ceiling grate registers, matching sets from the same late 1800s/ early 1900s home. I cleaned and wire wheeled the years of old paint off of the cast iron down to bare metal the best I could and sprayed them Rust-Oleum satin black. They could be sandblasted for a better appearance but I don't have the equipment. One register has a small crack that can be easily repaired with JB WELD or a Steel putty stick. One of the floor swivel registers has a longer crack but can be repaired the same was. See highlighted photos for both cracks. Any questions please feel free to ask. Thank you!
