The following weapons were used in the film Ironweed:
Francis (Jack Nicholson) remembers in a flashback a 1901 trolley strike in which there are US Army soldiers present to defend a Trolley conductor from an angry mob. All the soldiers are seen carrying and firing Krag-Jørgensen Rifles.
1903A3 Springfield Rifle
During the same scene, one angry mob member attempts to attack the train conductor, but he is struck in the face by the Army commander's (Jared Swartout) rifle butt, the rifle in this scene switches from a Krag-Jørgensen rifle to a WW2 1903A3 Springfield Rifle, which would be anachronistic to the time period as the flashback takes place in 1901 and the 1903A3 was made during the 1940s, the weapon also appears to be a non-firing prop rifle and was used most likely as a real rifle would be heavier and would hurt a lot more if the butt were to strike someone in the face.
