They look like WWI-style 'Brodie' helmets (something I just learned, looking it up ) https://en.wikipedia.org/wiki/Brodie_helmet A couple million were produced for Civil Defense use in WWII, so it's likely this is what they're making, as the familiar Mk1 GI Helmet was in production by '42. (again, per wikipedia https://en.wikipedia.org/wiki/M1_helmet )

I have a vague memory of pictures of US troops in the very early part of our involvement showing up for basic training and getting issued the old 'doughboy' helmets.
