I'm glad to see the 'TEASER' return, nice to have some fun sometimes. I think GG is right about the Dragoons and grenadiers a chevals. I'm not so sure about the chasseurs a chevals. Those guys could be Austrian hussars or Saxon chevaulegers.
What about the Napoleonic infantryman; he's in red makes me think he's British. Is that a sword he's holding or is that a bagpipe? Could he be a 71st Highlander( Highland Light Infantry).
