Hi BriteLite & MadDrDevo,
Firstly welome to the forum, I hope you have a great time here with us all. As 90th said if you use the search facility you will uncover a wealth of information.
I use uniform reference quite extensively and if I was going to offer any advice I would say;
Buy for starters something like Osprey Campaign Series 14 Zulu War 1879, this gives the Order of Battle for 1879 and lists the coloums and units attached to those colums. Also some good stuff on uniforms. Once you know the units you can can start breaking down the uniforms, equipment and weapons.
Osprey Elite 032 British Forces In Zululand again a good reference book.
Osprey Men At Arms, Zulu War - Volunteers, Irregulars & Auxiliaries. Excellent book again for reference on the uniforms both descriptive and illustrated.
Uniforms & Weapons of the Zulu War by Christopher Wilkinson-Latham
I'm sure if I have missed any sitters for starting, the rest of the brigade will chip in. If you want anything else please just ask there is a wealth of information and everyone is very helpful.
