German archer auxiliary??
sorry mate but i think they are more magyar like, i am not familiar with their traditional clothes but for me it looks like i don't know like some Hungary Archer cos of his helmet and as i already said his clothes, i am quite sure that i saw this kind of clothes on some Puzsta Riders. And before i forgotteGerman archers in an Serb army sound really, well you know strange.
If this are really german archers then they are probably meant to be Banat German Settlers, wich mixed their clothes with some Banat Magyars though, i am not sure. You should ask Sarmatian i think his from the Banat, i think.
P.S JUHU this is my 50th Post Muhahahahahahah
