I say its your deer, you harvested him. Mount him the way you want him. There is nothing illegal or wrong with fixing a broken point long as you don't get him officially scored. Thats the only concern to me. If to score or not. I do taxidermy, and have repaired broken points on mounts. I would never add non-existing pts for anyone. The way I see it is that buck roamed the woods with all his pts, and w/o them. Who knows how it got broke. Some hunters have previous trail cam pics of a buck before a pt was broke. So it comes down to personal choice of whether you want him as he was, or as harvested. But its ALL your choice, its YOUR deer!!
