Well, as I implied I haven't really taken very good care of these figures and there's some very noticeable dust particles on them in these pics but they should still be decent enough to use as a comparison. Also, when I made that previous post, I had only been looking at Rin and Ilya; you are correct in that Saber's arm is definitely at a different angle. In fact, she looks different enough that I had to check to see if I'd even grabbed the right figure. I am positive these are authentic though, as they came completely sealed in a case of individual boxes with the Type Moon seal of authenticity. It may just be that she's leaning a bit too far forward or that I didn't put her together properly.
Anyway, pics are here, linked because file size is way too big:
