Good people of the forum. I've had this for a while, I got it quite cheaply.
The thing is, it bothers me. I can look at it one day and think it is ok, the next it looks just wrong!
Liner is a Westinghouse. I do not think the liner is original to the helmet. The lid is front seam swivel bail. Believe it is post WW2 "Korean" repaint. Note the overpainted officers "aiming stake" to the rear.
