This is a cold weather mask that belonged to Jim Hornshaw while he served aboard the battleship Wisconsin during the Korean War. Jim served as a boatswain's mate first class and as gun captain of turret #3 on the ship. It is currently on display in the museum's Cold War gallery.
Wisconsin's tour in the Korean War was during a frigid winter of late 1951 to early 1952. Veterans of the ship during this time period recalled unable to stand watches outside for more than 15 minutes before having to rush back inside to warm up a little.
