For the Bob - photo 22 should show some numbers etched in the bolt on that side but there are none. I realize there is some glare present. Photo 34 shows what appears to be a re-strike on the proof mark. The oval is in two pieces and there appears to be a lighter blued color surrounding it. Look at the solid proof mark on the action to the right.
Furthermore, the "mint condition" of the barrel doesn't match the few handling marks on the stock.

For the '06 SG - photo 11 shows what could be pitting marks on the bolt handle covered up.
Photo 48 also has what looks like a re-strike on the proof mark. Notice how the ovals do not connect and are in two spheres. There also appears to be a blued color shift around the perimeter of the proof mark.

Other than that, they don't look too bad.

Caveat emptor.
