David, I think there is room for many more sets in this range, both irregulars and regulars for both sides. We tend to think of Arab irregulars , Turks and Brits, but there are French troops, Italian, Egyptian,and many others from the greater Arabia area. So the potential for a range is quite expansive. It has unusually for WW1 the romance of the desert and lots of colour for painters,I could come up with a dozen requests for sets, all of them would be a first for the hobby and all would be a part of the jig saw that is the Arab revolt.
