Missing brow tines. If your interested, I know someone who could fix them to a perfectly undetectible state. What does it look like at the point they are missing? If the edges are sharp, recently broken by fights or hard gougeing on trees. If rounded and polished, broken early after velvet lose. Usually, any damage in velvet will result in something being bent. If something does get broken while in velvet, it will not fall off, but heal with the break and a kind of knot look at the break. I have some sheds that are as such. If I have the time, I'll try to find them, take some pics to show.
never say never
