Hi there Jason
Fully agree there were many more small colonial mounted units serving in the other two invasion column and assigned to protect the Natal side of the border ( Natal Hussars etc )
I always hoped that John Jenkins or TG or King and country would bite the bullet and focus a range of figures away from the ever popular Rorkes drift and Isandlwana by say concentrating on Wood and Bullers column at the Battles of Hlobane mountain or Kambula, great character figures could be modelled in including Woood and Buller themselves , Piet Uys and his Boer volunteers , Natal native horse plus there colonial officer personalities and NCOs etc , Transval rangers , 80th Regiment , the 5 winners of the Victoria Cross and of course the Frontier light horse .
maybe John Jenkins will come to our rescue to focus on the forgotten part of the Zulu war ( unless you collect 28mm as these units are well served in this scale by Empress and Perry to name a few)
I too remain a devoted collector of TG
