I would agree 140's would be a decent guess, but kind of hard to tell from these pics (and being uploaded to the computer). As far as age, really hard to tell from these pics IMO. Do you have any pics of his whole body? I think its a lot easier to age deer from looking at there body's. But from these I would guess he would definitely be a giant! The other major thing to consider is, will he be able to survive another couple years? Does his home range provide enough "protection" from other hunters and what not? How much pressure does he see/feel? ......
