US M1 helmet & Liner Help

[carolinaskies]

I picked up this chrome M1 & Liner last week. I am trying to get a firm grasp on it's age and value. I don't have any books on helmets so figured you guys would have more sense for value. Could they have come from the same fellow or might they be a marriage of two separate pieces?

The fellow I bought them from thought they were post-WWII Occupation or Korea. I'm pretty sure they are post WWII, just not sure how late they might be.

The liner is marked inside in the crown "US 25" The only stamping I could find in the helmet was M 322 C and it's a rear seam.

The shell and the liner appear to be Vietnam period. The liner suspension system is the one adopted late in 1960 and the chin strap was used from the Korean War through to the 70's if memory serves.
