I've got some more Zulus on the way but I finished these four Foundry musketmen today. I have to say that I think that they are anatomically superior to the Empress ones but then they are based on some of Mark Copplestone's Darkest Africa masters. Although they are somewhat larger than the Empress figures it isn't that noticeable and I am happy to put them in the same unit. The guns are much larger than the Empress ones, however.
I've also just picked up Ian Knight's latest thudding great tome on the Zulu Wars. Zulu Rising. which, at 600 pages, I haven't had time to even glance at but it should keep me moving the next batch along..
