Now, I'm no expert, but this just doesn't look right to me, aside from the reworked bolt handle. The US 1906 stamping looks a little too sloppy to be Mauser work, and the stippling doesn't look like Mauser factory work either. The radius cut in the receiver ring appears to have been done after the stippling, as it's cut into the stippling. The checkering on the forend and grip don't appear to match either, although they're not pictured really well to be able to tell for sure. I'm also curious why he didn't take a picture of the markings on top of the barrel in front of the rear sight.
