Oswalds rifle is not a 'Mannlicher-Carcano' just a Carcano. Mannlicher is a completely different company,often assocaited with the Carcano because of several shared parts. It is the same as calling the rifle a Mauser-Carcano, i.e. completely wrong. And it was hardly an awful rifle, infact Carcanos were used by the Italian military up until 1945, and are easily accurate enough up to 300 meters.
