Not much.As for the sheds, on the NASHC forum I was told that there are 8 recorded sets of these in the world. I will sometime have to get a certified "NASHC" measurer to put a tape to them and I guess they can go in the NASHC Record book. As for the head, I boiled it and bleached the skull and it looks real good (and weird). I will try to post some pictures of it sometime maybe
