Can someone help me identify these helmets?

[Unheilig]

I apologize for the my absence. I appreciate all of the replies as they have been most helpful. We managed to unpack several more boxes and stumbled upon many more hats, caps and of course helmets. I also now have a massive collection of canvas ammo belts, slings and other assorted items that are dated 1918 and such. I've become so engrossed in researching everything I find! I must say, this has the potential to become quite the addicting habit.
