From my own personal collection!"Sniper's Delight - This intricate bit of business at the end of a 1903 Springfield rifle was designed during the World War for shooting from a trench without exposing the gunner. The rifleman sighted through a periscope. William L. Murphy, curator at the small arms museum in Springfield, Mass., demonstrates for the cameraman. Watch release date, Sunday, Sept. 29" 8/29/1940
Weapons that soldiers can use in combat while not subjecting themselves to return enemy fire is a recurring theme in small arms design. The Springfield rifle above is just another example; THIS and THIS are more recent ones. Modern technology has changed the look of the idea, and it has certainly become more practical, but the underlying goal is exactly the same as it was nearly 100 years ago.
