Chewbacca, what I've done is switched the second red button on the ESB, the one that acts as set screw, for the glass "eye" bezel set screw fron the ANH. It may not be 100% movie accurate, but it makes the ESB easier to spin while retaining its look. 8)
I've considered trying to switch around some of the other parts too, such as the grip ends and clamps, to create a unique but still recognizable Graflex.
