Brad,
I assume you subscribe to Toy Soldier & Model Figure magazine. If not, why not? In any case, there will be photos (I hope) of many early sets with their official box end-label description in the next issue. Regretfully, I do not have any price lists before set No. 29 which started the Zulu War range. I pretty much have everthing going forward from that point from Stone Castle's descriptive price lists. For example, set No. 29 - iNdlondlo Zulu Regiment, 1879 is described as "3 Zulus with clubs & 2 with stabbing spears (brown & white shields)." Imperial also produced separate color product sheets with photos of the various sets from the Zulu Wars, Sundan, Crimean War, etc.
