scroll down, the picture they have of a old EQ gm event has 2 halflings wearing the helm....this was the original color and look of the helm (green/plate)
edit: Id like to add that cause of the fact that it's 2 halflings wearing the helm in this shot im alittle worried that this might be some halfling noobie helm quest i dont know about in this particular picture, however I never played a halfer nor did I do any quest resulting in a green helm, so I believe this to be the Turtleshell Helm as it is EXACTLY the graphic I remember it as. I wish I could find a better picture with someone atleast talking about it.....
