A set of Aico Auto bellows. These have a fast focus rail and fine focus, and have auto iris coupling through bellows for easiet use than manual bellows. You'll need some mounts. I have a pair of Nikon ones being sold separate.
bellows are damaged, everything else is good. You could buy a replacement set from Camera Bellows. Or use tape to patch over small hole. Also good for spares or diy project .
