Not sure I'd ever believe that age on that deer.  What a CRITTER!  Thats the stuff right there.
Believe what you want i have a lot better stories to make up than the age on a deer...... I understand that i have not posted as much as some people on here but i am not someone who is going to come on here are share false information. 
The taxidermist has been in the industry many years (over 30) and i have no reason to doubt his opinion. When my dad and him were capping it out and looking it over they said that it had all of the characteristics of a very young (3 1/2 to 4 1/2year old) deer. 
It was a very young generically blessed deer. 
I will see if i can find some better pictures. The eyeguards are 5 plus inches and his right side has three kickers off the back that you can't really see.
