Springfield 1903 Trench Rifle
Modified weapon fitted with experimental Guiberson trench periscope in stock. Weapon has a collapsible hinged stock and mirror periscope built into the stock. When not opened to the firing configuration, the rifle appears much like a conventional '03. M1898 rifle sight. Blued finish with checkered buttplate with well for cleaning rod, etc. Modified straight grip stock with finger grooves. Weapon enabled a rifleman to fire over the top of a parapet without rising over the parpapet himself. Tested, but never put into production because it proved to be incapable of rapid fire due to limited field of view. Missing mirrors. Date of Manufacture: 1916.
