I have no guess, but the whole age thing is very interesting to me. Yep, most of us want to kill a mature buck, but IMO most of us (myself included) can't tell one way or the other by looking. Even leading deer experts say that it is an "educated guess" at best and that in pen-raised deer situations they have had 1.5 year old deer look almost exactly like a 3.5 year old deer and between 2.5 and 5.5 it's even closer.
Aging by tooth wear is better, but still not close to exact. When I took my 2007 buck to the taxidermist he told me 5.5 after removing the jaw. Took that jaw to a DNR biologist and he told me 3.5 so I figured the taxidermist was not all that good at aging by tooth wear. The next year he aged my buck at 3.5 and the DRN guys agreed. Point being, hard to determine.
Good luck.
Oh, and...if they were both 3.5...the 2007 buck "Looked" older than the 2008 buck.
