Hey, so I finally got some time to dig through my photos on file.
I dove in focused on chinstraps and I gotta say, I am becoming a WW2 helmet believer.
Check it out
-No T1 'ball' extensions at all. This would indicate pre-1945.
-It is super clear that Apone's chin strap is SEWN into place rather than being secured by clamped down steel hardware. They stopped doing that before the end of the war.
-Notice in all the below images that the securing hardware appears brass in color. The were only brass until 1943!!!
-The helmets largely appear more or less smooth. (not in the below images, but in virtually all screen grabs elsewhere).
In 1950 a fine sand aggregate coating was added to them. The smooth appearence could indicate earlier WW2 era helmets as well
The only thing 'modern' about them is that they had swivel bales (which themselves do
not rule out WW2 use). Everything else indicates a much older helmet.
Wild stuff!

All the above details are covered in this link with better pictures. Scroll down to the chin strap sections.

I think that ship has sailed and the only argument that could be made is if someone can find a foreign version that did have the WW2 features. Otherwise, I am now in the WW2 camp.
