IS THIS EB II OR NOT??

[Atilius]

Can anyone confirm this? I'm not challenging EB's historical accuracy (which is nigh-perfect, if not perfect), but am merely curious. If the triarii helmet can be pulled down over the face, why would the troops wear it like that, I wonder?

That style of helmet is called Italo-Corinthian or Apulo-Corinthian. It imitates the look of a Corinthian helmet when it was pushed back on the head as one often sees on greek vase paintings. The Italo- or Apulo-Corinthian helmet was definitely never intended to pulled down to cover the face: the eye holes are much too small and I doubt it would sit properly on the head even if you tried to do so.
