That is a sweet mount! Nice trophy. Congrats to your brother. I have one at home that is just slightly smaller than this that goes low 140's, so I would say this is around 150 - but he is very symmetrical and well proportioned. From the looks of the original pic, he may have been a young buck? Curious to have seen what he looked like a couple years down the road.
