Roger Craig identified the rifle as a Mauser due to the stamp embedded on the rifle. That is a solid eyewitness account.
Weitzman also agreed it was a Mauser as well. He was an owner of a sporting goods store so he was familiar with rifles. When he testified later, he changed his story and claimed he only "glanced" at the rifle.
That's an absurd statement to make. Why would a Sheriff just "glance" at the potential murder weapon that just killed Kennedy? He would give it a thorough inspection.
Weitzman changed his story and Roger Craig never did.
Whaddaya mean Craig never changed his story?
In '68, when he and Penn Jones were interviewed by the LA Free Press, Craig said that he didn't know what the rifle was.
In '69 at the Shaw trial, Craig was shown a Carcano and said that the rifle Boone found looked like it. He said nothing about seeing "Mauser" or "7.65" on the rifle, even though this was the perfect time to do it.
In '71, Craig wrote "When They Kill a President." In it, he said nothing about seeing "Mauser" or "7.65" on the rifle, noting that it was identified by Weitzman.
Only after that, in the "Two Guns in Dallas" video, did Craig claim that he saw anything stamped in the rifle. This story is directly contradicted by what Craig said to the LA Free Press. It's also contradicted, though more subtly, by his Shaw trial testimony and his own magnum opus.
