we see the merits of your suggestion, but at the moment we're working on late war Serbs. You're right, that they, ideally, should look like French, but we will retain some unique national features (like we did with WWII Indians, etc.), and, if mixed with the French from other manufacturers, could represent this specific army.
We shall see how this set will sell and, depending on that, will decide about further sets.
In the meantime we're working on another WWI unique subject, not covered yet at all. Follow the website for updates.
Photos tend to show serbs wearing tunics and breeches rather then exclusively the capote(overcoat) mixed in with British army tunics and usually a Serbian type Hät though I'm not sure if its a french made version or not, generally a very mixed bunch
