Horses from Ibn Saud as gifts to Egypt’s King Faruk’s wedding

Look what I just found in the archives of the Egyptian weekly newspaper Al Ahram: a recent (2006) article citing a much  older (1938) Al Ahram article reporting on the january 20, 1938 wedding of Egypt’s king Faruk to Safinaz Zulfiqar, who became Queen Farida. All the article is interesting, but what is most remarkable is this sentence: “Al-Ahram presented a register of the gifts that states had presented to “His Majesty the King of Egypt”. Ibn Saud, the king of the Hijaz, presented four horses “that are pure-bred from 400 native horses. They are “Kahilan, a colt, Al-Saqlawiya, Abiyan, a race horse, and Al-Jilabiya. The name of each is traced back to the names of the Arab houses that have preserved them since the ages of the first Arabs.” What happened to these horses? Do you think we can find their trace in the Inshass Original Herd Book?
