I bought this several years ago on another forum for antique reloading equipment. I thought it would fit on my old C-H single press. It didn't. Its made of what feels like cast aluminum, as you can see grey in color. Only markings on it are the numbers on the back. A parts number I think. Across the throat it is 1.414 inches. [img]
