After a closer look I can see what the problem is clearly. It is as I thought. Someone tried to close the front panel when the focus rail was not in the "close" position. This bent the rear left in body rail and to some degree the right one up about a 1/16th of and inch. The front moving rails are connected to the rear by a link on each side and with the rear rails pushed up as they are this freezes the front moving rail. I think what I am going to do is use the focus rail system from my other Crown Graphic on this body which is in much better shape. The push rod for the rangefinder system is also bent. If I can successfully straighten it then I think the rangefinder will works as well. Considering it's age this camera body is in very good shape.
