The product is a vintage antique cast iron 2 wheel double block and tackle pulley with a rope brake. This collectible pulley belongs to the tools and hardware category, specifically in the pulleys, block, and tackle section. It is a durable and historical piece that can be a unique addition to any collection. You might even be able to restore it to practical use. Clever little device. There's a lot of wear, but you can almost make out a patent date. Perhaps you can clean it up and read it better.
