The shutter seems to work well. It's very clean, except for the verdigris you see in the photos. The handle is in good shape (not that I would trust an 80 year old handle). There's a small tear in one of the front cover curtains. The Cooke lens aperture works smoothly. The front cell unscrews easily. I didnt want to risk damaging anything so I never removed the lens body from the mounting ring, or the rear cell from the body. There's a little haze at the back of the lens (that might come clean if you want to take the lens out to clean it properly) but I don't really think it matters. More photos on FLickr
