I'm somewhat surprised that I do not see more comments on the many manufacturer's mistakes when it comes to a reveal style Darth Vader helmet. A huge Vader enthusiast, I have over the years become sharp at noticing the finer details to the the blatant mistakes. Though the technical terms are not my specialty, observation is! Take for example the metal attachments on the inside of the lower (jaw portion) of the helmet. Though clearly one is seen on each side in the movie (ROTJ), many fan made , and otherwise exceptional, helmets have only one. Another example that comes t mind is the new Sideshow bust. I think it is amazing, yet someone or many someones, failed to notice that on the forehead dental expanders, the upper set are smaller than th elower ones! Don't get me wrong, I don't mean to come off as a too good or cynic, but with the amount of money involved in these purchases, I would like to think that the attention to detail is a bit more serious!
