We have a Salvaged Metal Round, vintage item. I'm not sure what it came off of. It is about 7" across the center with the center hole being about 3/8" across the opening. The center is domed a bit with it being about 3/8" - 1/2" in H/d in the center where the hole is. I'm not certain what type of metal this is - it weighs just over 10 ounces, it doesn't stick to a magnet. There are surface scratches on it as shown in my photo's. I was hoping someone could use/repurpose this.
