The WC evidence that proves Oswald purchased C2766.

The proof Oswald possessed C2766.

The HSCA proof that the identifying gouge on C2766 was seen in the backyard photo

Oswald's print on the long brown paper bag found in the sniper's nest

The FBI's proof that the Lt Day print came from C2766

A tuft of several fresh, dark blue, gray-black, and orange-yellow cotton fibers was found in a crevice between the butt plate of the Carcano and the wooden stock. The FBI laboratory found that the colors, and even the twist of the fibers, perfectly matched those on the shirt Oswald was wearing at the time of his arrest. Though such fibers could theoretically have come from another identical shirt, the prohibitive probability is that they came from Oswald’s shirt.
