The load of garbage is you showing a photo and just claiming that it's the same rifle.
Yeah, I know. Yellow blobs.
What a surprise that you "can't" see the same gouges in the same place on both photos, how predictable!
Instead of telling us what you think you see how about you present the HSCA evidence to someone reputable and get a definitive answer because really John, a personal opinion from Oswald's Defence Lawyer isn't worth the paper it's written on.
