Karak-Kaifa and Chouk
The photos of the two stallions below come from the article, ‘L’Opinion des Arabes sur le cheval’, printed in the 3 March 1900 issue of Le Sport universel illustré.

Kapa-Kaifa [sic] (above) was a 1894 bay Kuhaylan ‘Ajuz stallion, purchased in Kaila, Syria. I am not certain that the name of the horse, nor the location where he was bought, are spelled correctly, given the typo ababe for arabe in the caption. Edit: See Edouard’s comment below, identifying him as Karak-Kaifa.
The photo of Chouk (below) was reprinted by Lady Wentworth in The Authentic Arabian Horse, where she criticised it as an example of poor presentation of a good horse.

Thank you for posting these! That would be Karak-Kaifa, a d.b. import who still has a line going in Tunisian asil pedigrees
