If it were a doe and I had to go on tooth wear ALONE, I would say 3� because the lingual crests on tooth #4 are certainly losing their sharp peaks and the inner dentine there is probably wider than the outside enamel.
But I never feel 100% confident separating 2� & 3�, whether it�s body characteristics or tooth wear.
I concluded 2� due to the light body weight and small antler size, but I could easily be wrong. I can post you tooth wear pics from him if you�re interested. I may just send a tooth out for microscope analyzing because it�s fascinating to me.
BTW, this is SE PA farm country yet only his one antler qualified for our state implemented 3-point AR (1� tine length minimum). His narrow spread would not have made him vulnerable for harvest any earlier either (had there been a spread exception to the point rule). Of course he was fair game to jr. hunters though.
