The Oswald rifle is an Italian "Fucile di Fanteria" (Eng: Infantry rifle) "Modello 91/38" (Model 1891/1938) manufactured at the Royal Arms Factory in Terni, ("Regia fabbrica d'armi di Terni"), Italy, in 1940. The stamp of the royal crown and "Terni" identifies this manufacturing site. Its serial number identified it as the single weapon of its type made with that number. The so-called Model 91 bolt-action rifle had been introduced in 1891 by Salvatore Carcano for the Turin Army Arsenal. After 1895, the Modello 91 used an "en bloc" ammunition clip similar (but not identical) to the Austrian Mannlicher ammunition clips, and hence the names of Mannlicher and Carcano came to be associated with the Oswald rifle; this included association with them by the Warren Commission. The ammunition used in the clip was the 6.5×52mm "Cartuccia Modello 1895" rimless cartridge (designed in 1890), also sometimes called Mannlicher–Carcano ammunition, after the rifle designer and the general type of clip it used.
