Sheep Head Nepal Antique

Found this really remarkable piece. It’s a sheep’s head on which human head is displayed. It’s made of wood with natural horns. Copperwork details. As you can see it’s fairly damaged ans some bits are missing. At some point has been stuffed with magazine paper to prevent implosion. Origin: Nepal. Age: 150-200 years old. Not sure about the stones, but I assume it’s red coral and onix.
