The camera seems to work, even on the slower shutter speeds, and the curtain looks good. Other than the leather covering, I note two other issues with the camera. One, the little red window is missing. The other is the deceptive angle mirror is cracked and part of it missing. Both of these are easily fixed. More photos on Flickr.
