Louis is probably the best person to answer this but there were Seaforth Highlanders (Last Stand of the Seaforths), Napoleonics, Lancers, Zulus, Afghans, Camel Corps., marching bands (tons!), Rough Riders (made for Kings X), some World War II (the First of the Few RAF set) and so forth. If you come to the Symposium, you'll see them all. Streets of Hong Kong were glossy at first. There's also early U.S. Civil War glossy sets. It's all great stuff.
Take a look at Bill Sager's site, the Brochures section and you'll see what I mean.
