Great work the weathered one could be the real prop,
Though one thing I did notice today when watching ESB (though Im sure you looked at heaps of reference mateiral so I may be wrong) the nose on the real ones seems to stick out quit far almst like the stormtroopers as if it was cut off at the teeth, and the cowl sort of hangs down from the point of the nose, if that makes sense,
How ever once again another great sculpt from you , knees look great , Imlooking forward to seeing you do the shoulders
