Video of very interesting Heck bulls

Recently I found a video of two very interesting Heck bulls on youtube:

The horns of those critters are astonishing, especially those of the bull at 0:50. Unfortunately the video gives no information on where it was shot, and has comments disabled. But not only the horns but also the body shape (sloping back, sloping pelvis) and the looks of the face makes it very likely that those bulls have Watussi ancestry. Furthermore, the shoulder hump and the solid black colour reveals influence of Taurus/Sayaguesa, which makes it very likely that they are Hungarian Taurus cattle and that the video shows one of the young bull groups of Hortobagy. 
Not only are they very interesting to look at but they also give a foretaste for what the Watussi crosses of the Auerrind project are going to look like.
