Sorry NitroX, but that is not a simitar oryx, but a giant oryx, aka gemsbok, native to southern Africa. The simitar horned oryx is almost white in color, and the horns are shaped like the Arabian simitar sword, and, in fact, are native to Arabia, and parts of North Africa!

Both beautiful trophies and good pictures as well!
