Well I've rebased my slingers and archers for my Ancient British/Gallic army. The exact mix will depend on which army I'm playing as the Ancient Britons almost entirely used slingers
I've mixed up the figures somewhat so each of the original airfix slinger or archer is accompanied by a different figure, either from another set or a conversion.
The result is that I still have a number of figures left over. I think I'll mix the remaining archers with some Revell Saxon archers so I can use them as Ostrogoths or Visigoths. I'll need to find some more suitable donor figures for the remaining archers, but I wonder how often I will need to deploy more than 48 slingers (I'm allowed up to 150 under WRG 6th edition)
