Shells are often refurbished every now and again, as this one probably has been.
The first place to look to date these would be to look under the peak in the front for numbers/letters stamped in the steel.
The shell very well could be WW2 vintage, just refurbished later on with sand texture and the light green paint. It would be hard to call it WW2 vintage though.
Regardless of front or rear seam it needs to be stainless steel to be of WW2 manufacture,by stainless steel I'm referring to the seam only,not the manganese steel shell...

Simplistic, but it is what it is and sufficient for your purposes.

Actually the manganese rim was used during WW2. Its introduction roughly coincided with moving the seam from front to rear, so you can sometimes find rear seam stainless. Most rear seams WW2 shells, however, are manganese.
It is possible it could be WW2. There were rear seam helmets made in late 1944- early 1945. This helmet could've been repainted to be used during Korean War. The markings inside are just how they kept up with steel. Numbers with no letters= WW2. Numbers + letters= WW2 and Korea.
i have two helmets one has a heat stamp of 1053 and the other is S1A with an S below it-can someone date it for me
Both are WW2 version Patches3. The S1a is a Schlueter which made less helmets than McCord.
