This M1C paratrooper helmet is a later produced M1C than the one that was previously posted. This is indicated by the rear seam and the olive drab colored chinstraps. The liner is a Westinghouse paratrooper liner.
This helmet and liner was found together by a picker about a year ago. This helmet is not identified, but I was still very happy to add this helmet to my collection. It has become very hard to find these helmets in excellent like this one is.
