There are two other catalog sets of HIRIART Royal Artillery: 1114 Royal Field Artillery Gun Team and 1248 Royal Artillery Gun Team, Colenso, Boer War. I don't have photos of either set, but 1114 is described as wearing all blue uniforms with red trim plus blue helmets and has three side riders and four seated artillerymen on the limber and gun. The gun is a Quick Firing 13 Pounder. Set 1248 is described as wearing all khaki uniforms and helmets with three side riders and three seated on the limber. Here is a photo of a non-catalog set similar to 1248 for India where they are wearing khaki tunics, blue pants with red stripes, and white helmets.
