The answer is Tunisian! Not Syrian, not old or new Egyptian, not Davenport, not Saudi, not Bahraini! Here are two more pictures of him at the Tunisian government stud of Sidi Thabet where his owner is keeping him. Enjoy.
This new-to-me photo of the Syrian Kuhaylan Mimrah stallion Basil (Mahrous x Halah), of the breeding of the late Mustapha al-Jabri was taken at the Damascus Government Stud . It recently appeared on one of the many Facebook pages now focusing on Syrian Arabians, one hosted by “Alhorane”. I remember being struck by this horse the first time I saw him in 1990. He oozed Arabness.
