Vintage Nautical Rope Fender Knot Buoy, Set of 2

Set of 2 vintage Nautical Rope Fender Knot Buoys. They are roughly 16 inches each from the base to the top of the loop and weigh around 2.5 pounds each. They were picked from the out building from an estate local to me and are still a bit dusty from hanging on the wall for an unknown amount of time, but are just in absolutely amazing condition!
