Mark, Good analysis. That is something I had not considered, which was the facings could be white - I hope not - because then we are "all at sea" as to what this uniform actually is. You are correct - the photo is from the Cairo Military Museum. I suspect/ my research indicates that the Khedivial staff were likely to wear standard Turkish uniforms, and the photo of KHEDIVE Abbas Hilmi II of Egypt (attached) very much demonstrates this. However, note his shoulder boards - here is wearing a M1879 Ottoman Turkish summer Marshal?s uniform (three large Silver shoulder board stars) including British Marshal?s crossed battons. I have found an interesting set of references to the Egyptian army uniform, in Sidney Low, "Egypt in Transition" . The London Daily Chronicle. Reprinted in New York Times (2nd May, 1915). "The British Officers in the native regiments were merely ?lent? to the Egyptian War Office for the service of the Khedival Army, which was technically a branch of the Turkish forces, with Turkish badges and Turkish insignia?. Paintings in the National Army Museum (london) from the 1890s clearly show Egypian soldiers in British summer uniforms but with Turkish insignia, and this does explain the number of british made Turkish buttons that seem to be about. As to the Khedivial guard regiments of horse and foot, these clerely wore copies of the Sultan personnel Infantry and Cavalry, which were the again similar in pattern to the 1st Lancers, and the Ertugrul Cavalry regt.
