Someone reviewed the plastic Wargames Factory Zulus on The Miniatures Page and, like me, thought they were pretty good.
Interestingly, he had the same problem as I did in that he couldn't get the arms holding a musket in a shooting position to stay in place. Empress Miniatures don't do Zulus in a firing pose and the Wargames Factory ones don't work so I think I will have to buy the Foundry ones despite their overlarge muskets.
I finished my first Wargames Factory plastic today. I have a few Empress and Foundry figures nearly done too so hope to put a comparison shot up at the weekend.
