It is hard to find more balanced and better conformed desert-bred horses than the 1999 Syrian stallion Jurnass (Ghaseeb x Raya) and his close relative Zayn al-Khayl (Ghaseeb x Raghdanah), both Rabdan by strain. Photo of Jurnass from Facebook, not sure who took it originally.
I just stumbled this AK PTF update from 2013. The early 2010s were a critical time for many of lines, as many breeders/owners were reeling from the impact of the 2008 financial crisis. However, most of these horses went to good breeding homes, and now have descendants. Ten years later, the results are encouraging.
