vietnam war helmet

Description

For sale is a Vietnam War US helmet. The helmet appears to be a Korean War era helmet, as it has a cork finish on the steel pot and it is a rear seam. It also has a WW2/Korean war helmet style liner with the leather band that goes around the steel pot. It is in good condition all around.
I don’t know much about Vietnam war era helmets so please ask any questions and I’ll do my best to answer.
Thanks.
