Post war or late war M1?

[JustAGuy1250]

Hello,

Is this M1 late or post war?
There is: 1S478 stamped in the front and is a rear seam helmet

I would say late wartime, but not able to see much detail from the photos.

Hi there,

the color and the clips speak for a factory revision of this helmet in the 1960s. And thus use in Vietnam and later.
