I have nearly finished my first sixteen Zulus from Empress miniatures. They aren't perfect but look very good en masse. The faces are good, some very, very good. They are a little small some of them, compared with the British, and the anaotomy is not as good, say, as Copplestone's Ngoni (particularly the arms and legs). The real problem is the chest area where the relationship between the deltoid, pectoralis major and clavicle is not quite right. Odd, as the sculptor has modelled the stomach area really well and caught that pot-bellied look from contemporary photographs. Still with a shield and weapon it shouldn't be too noticeable.
Empress have come out with two more releases in the last few days. Firstly, some Zulu's with the classic cow-tail decoration on arms and legs. I am going to use these as unit leaders as in battle these decorations were unlikely to be (but not never) worn. Secondly, a set of British heads, four with Glengarrys and four with the (white) helmets with badges on (as seen in the original film Zulu and also worn by the 99th foot). This deals with the issue raised by Lt Col Mike Snook, in his review on the Rorke's Drift VC site, regarding the trumpeter having a helmet cover, which didn't come in until later in the campaign.
I have ordered two packs of the cow-tail Zulus and the head set. My experience co far with Empress is that their dispatch is very fast.
