18th Century German States Painting Guides
There are some nice color plates on this site showing the uniforms of the German states in the 1700s. I don’t know German, but by looking at the plates, I think that they’re all from the Seven Years War. The first page is definitely Frederick the Great and his generals. Someone with more epertise in either the period or in German will have to provide more detail.
