The first gun I ever owned was a surplus Carcano Cabine, yep just like the one used to shoot Kennedy. My Father had to go with me to buy it as IO was in Grade School. I'd picked up coke bottles to save the money to buy it. I think it cost $16.
Years lkater a cousin wanted to buy the same gun Oswald used so I sold it to him. He never paid me.
I do have the murder gun from the first Homocide I ever worked, 1978, and the first pistol I used in a shooting, 1980.
