Intriguing bit of tiny evidense that makes you go hummm.
The Bottom Sling Mount
The rifle found in the Texas School Book Depository had a leather sling attached to it. The sling itself is believed to be a strap from a United States Air Force holster, and it is mounted to the side of the Mannlicher-Carcano by means of an oval ring (see photo right). Also note, that there is no mounting ring on the underside of the rifle.
On the day following the assassination, Lee Harvey Oswald was shown a photograph of him holding a rifle in one hand, and two leftist publications in the other. Around his waist, a holstered pistol. Immediately, Oswald told Captain Fritz that the photo was a fake, that someone had superimposed his face on someone else's body.
The backyard photo (CE-133a) appeared on the cover of Life Magazine on February 21, 1964, as well as several other magazines and newspapers shortly thereafter. Although Oswald's claim that the photograph was a fake was not publicly known until the release of the Warren Commission Report, several critics came to the exact same conclusion based on conflicting shadows and other inconsistencies in the photograph.
Closer examination of the photograph reveals that the rifle being held by Lee Harvey Oswald is not the same rifle found on the sixth floor of the Texas School Book Depository. Notice the circular mounting ring attached to the underside of the rifle, and compare it to the photo of the rifle found in the Depository. I have marked it with an "A" at the spot which the circular ring appears on the rifle in the backyard photo of Oswald. The mounting ring, so clearly visible in the backyard photograph (see close-ups below), does not exist on the rifle discovered in the Texas Schoolbook Depository. They are not the same rifle.
I've included close-up enlargements of the mounting ring along with some digital enhancements. The top left is embossed, while the top right uses edge detection. Both show that the ring is part of the rifle beyond any doubt.
The bottom left is not enhanced in any way, and is included for easy comparison. The copy in the lower right has been lightened to the point where the background blanches out. This clearly demonstrates that the mounting ring is not part of the background shrubs as some have claimed. There is no doubt that there is a sling mount attached to the barrel band that was not present on the rifle found in the School Book Depository
