What makes you think he's that old? Knowing where you live would help as far as whether I'd think about shooting him. He's a nice buck, but if he's as old as you think he is I'd shoot him because he probably wont get much bigger. On the other hand, if he's only 3 or 4 he could double that size rack when he's 6 or 7 if he lives that long. I'm not going to give a score guess on the thread, but I know about what I think he would go and it would depend where you're at whether I'd shoot him or not if I got the chance.
