Sewing machine wheel?
Found this near a 1700's era cellar hole in northern Vermont. Roughly 6 inches across and very heavy. I'm guessing it is a sewing machine wheel, but after searching hundreds of photos of vintage sewing machines I've failed to find anything as ornate. The outer edge is indented, which I assume threaded a leather strap/cable. I've cleaned it up, of course, but it was about 8 inches down and pretty rusty when dug. Any ideas?
