Somethings from a mill?

Sifting Devices
Sifting Devices

Another early picture, and another one from the Isle of Wight, Calbourne Mill to be precise. I’m not sure what these were for. Some kind of sifting things, but I don’t know the real name. I liked the position of them more than anything, and I still do. The picture quality is very poor though. I know that. Even so, I still like it.
