I could not access the chain mail sections of the texture so that's all I could do but could clean up the fur. (can't cut any part of it either)
If you want just the helm, only drop the file that ends with 198 in your tex override folder.
(inb4 the white is too white comments- I like it! Seeing as most zones are rather dark anyway, the pure white never bothered me really.)
Enjoy!
