A friend obtained these 2 hats from the estate of a deceased WW2 (US) veteran.
They were obtained together.

I have no doubt as to their originality, or that they are DRB related.

They are late-war pieces. The body is a medium-blue, but with a green band and piping.
(the chincord buttons are shoulder-board sized, but I have seen that before on other hats).

Has anyone seen anything like these, and if so, and idea who wore them?
(I am thinking they were for wear in one of the Occupied Territories, but I am not sure which).

Here is the visor:
