I have this piece of tackle that I cannot identify or how to use it. I know it is at least 50 years old. It was in my father-in-law's table box. It measures 1 3/4 inches long. The black circle is 1/4 inch and has hole in the middle. It is one solid piece and does not come apart. Thanks for any assistance.
Mine opened. Here’s the picture.
