That is kind of what I thought also. The screw would swap with my 24, or other late Diana. It looks OK and works OK. Probably a hard item to find, so I will live with it. The gun isn't totally stock, but a very nice shooter. Perhaps in the future I will run across a looker as well as a shooter. Still not disappointed, as they rarely come up for sale, so I will still enjoy it. I knew going in that it wasn't collector grade.
