Answer
Here is an answer I found when I googled fat 42, there were lots of others answers so you google it you should find more info.

Your rifle is an Italian military rifle known as a Carcano. It was manufactured by Fabricca Armi Terni, the Italian military arsenal, in 1942. There are several versions, yours is probably the "fucile" or long rifle version. It should be chambered to fire the 6.5x52 mm (or "6.5 Carcano" or "6.5 Italian") round, but some fired the 7.35mm Italian round, or the 7.9 mm (8mm) German Mauser round.
