The dates are correct. I've never really seen the differences in antler growth from year to year on the same buck, so I'm not sure how much things can change...
I would say yes. On the left side the g2 is shorter than the g3 in both years and the rack has a similar shape. The only thing that gives it a little bit of doubt is the brows.
I agree with Dan, the only thing that makes me doubt it are the brow tines. Beautiful deer through. Good luck poking a hole in him this year!
