No disrespect taken. Its all speculation, look at the first photo. Tells you nothing right? Now look at the lateral view of the second photo and zoom in on it. First Premolars are gone - thats automatically Older than 2 1/2. Now look at the gum line in the lower jaw, its still there even though he removed the hide. Six teeth left. First tooth worn, second and third worn almost to the gum line, 4th, 5th and 6th worn to the gum line or gone! It would be easier if you had a topside view obviously. Thats an old deer. If you look closely he actually has a bad cavity in his top fourth tooth. We have killed 5 year old bucks which have a lot more enamel left then that. I think you did this old boy an obvious favor as he probably only had a good year left. But like I said it depends on region and year round forage. We hunt in Michigan. Save your jaw bones, you will start to notice similar wear patterns in your deer that will help you age them. Then again its all just speculation. You don’t have to believe me, but I’ll trust myself more then the Wisconsin DNR rolling a bee bee over the teeth to age them.
