Wow thanks for the responses . I guess what made me really notice the difference was I recently saw a helmet for sale with a really high brow. It looked like a TK except in the description it stated it was an unwethered sandy, so that is in line with all the above. And yeah I guess ANH TKs were all over I did a little digging here and there was a shot of a squad from what appeared to be right out of the film and the brows were all over the place. None of them appeared to be in the same spot.
