Okay. I know it's just a Carcano you bought from Joe Bob for eight bucks one Saturday night in the 60s when he was hurtin' for cash to take Emma Lou to the drive-in picture show.
The "SA" stamp identifies it as one of the Italian goofs in 7.35x51 (or 52, sometimes) that Mussolini palmed off on the Finns for their Winter War. The SA ("Suomen Armeija" or "Finnish Army") didn't much like it, but they were desperate and issued most of them to REMFs. Still, they're mildly scarce and a nice piece of World War 2 history. Too nice to run through your woodshed chop shop.
At least you didn't fool with the metal, meaning I need to find only a stock and furniture to have a "correct" if not fully authentic rack mate for the other iron from the 1939-45 horror.
Errrr. Forty bucks when the hammer fell Saturday, if you must know, and that's why I'm grinning, regardless.
