I owned one when I was about 16 back in 1964. Mine had all chromed metal except for the barrel and receiver which had a really good blue job on them. The stock had a blonde finished wood and was very smooth. I always thought that it was an honor guard gun, or parade gun. Perhaps someone had just fancied it up, I really don't know. I had traded a Swiss Schmidt Rubin for it because the Swiss ammo was very hard to find and I got 20 rounds with the Carcano, and it was more of a carbine, whereas the Schmidt Rubin was a long and heavy gun, although I had sporterized it and the grain in the Walnut Stock was absolutely beautiful.
Anyhow, I shot the Carcano, I can't remember if I fired all 20 rounds, but it was very accurate with the iron sights at 50 yards. I eventually traded it in on something else as the ammo was not available in Brownfield or Lubbock. There was a large gun store in Abilene, Tx that probably carried carried it back then, but the area around Brownfield did not have any deer that ever allowed you to see them.
Lee Harvey Oswald apparently thought very highly of the Carcano as that was his choice of a Sniper Rifle in Dallas, but Jack Ruby made sure he is not still around to expound on the Carcano. Yep, I love conspiracy theories!
