I am not a camera expert, but this appears to be in very good condition.  When you press the lever to take the photo a little metal wire clicks down which you can see from the front of the lens.  Also there is a button on the bottom, and when you push it one way, it clicks and also something inside the lens moves, so I think this is all in working order. This measures the front 3 1/2" x 5 1/8" and is 5 3/8" deep.  This is from a New Jersey house sale where it was very well kept and taken care of.  Please look closely at my photos for details.  Item 706 BB
