That's really informative, RBJ; thanks for sharing (was the RS pillbox handpainted?). If you wouldn't mind, could you please elaborate as to the few areas that are 'off'? I'm extremely intrigued by this!
And kinda off-topic, but besides RS and SDS, are there other makers/vendors who have direct lineage to the screen-used helmets? I see some makers who make very, very good and accurate helmets, but their origins are pretty vague... I'm not sure if they're castoff the original helmets, or are just extremely talented sculptors (Cal Pierce (Far Away Creations), DA Props come to mind).
