This is a United States Navy M-1 helmet from the Cold War era (1947-1991). The helmet shell is from World War II (1939-1945) but the liner of the helmet is dated to 1978, indicating that the shell was left over from the war and used at a later date. The grey paint on the shell indicates the Navy issued the helmet. The liner is typical of the time period it is dated to. McCord Radiator and Manufacturing Company produced the helmet shell while Firestone Tire and Rubber Company manufactured the liner.
