I was so lucky to see them in Dvur Kralove in 1982, the last animals in Europe, the last female died at 1.11.1984. I doubt we will see them in Europe again, due to the import ban (veterinary restrictions), they are not endangered species and not very attractive to the public, unfortunately...They have lived in a big enclosure, together with Topis and Bonteboks, another rarites which are not kept European zoos.
