can you get your hands on some sheet metal?
if so, it wouldnt be to hard to "wing it", otherwise, theres some tutorials, on SCA/LARP
sites, probably here too, try medieval helmet, or some such,
the hard part would be finding something to form it around, and joining the parts,
since you need some articulation, which you wont get if you just pop rivets in it
the "undermost" piece should be one solid bit, or make a "skull cap" and add the neck guard,
youll want the edges rolled in, then tap em flat,
the main helmet piece would be easiest to look at like a backwards trucker hat,
if you have a hard-hat or a large rock of proper shape, form the piece around that
leaving enough overage for the rear brim
(remember its not actually angled up, its jus all the pics show it in a facing down position)
the visor is a beast, shaping wise, so thatll be mostly "winging it"
it would be wise to roll all your edges, the reason thier not in the art or game,
is cause its not made from sheet metal, i think canon wise, itd be composite materials
just remember to start oversized then trim down,
make the helmet loose, youll want about an inch of padding or more (not compressed)
deburr ALL edges, it not only looks nicer, its safer
roll your edges down, or it collects lint and liquids (more so if you roll up)
