Western Kazahstan / Cumans / Petcheneg
Same sort of scales found in Rus (Donetzkoe), Volga Bulgaria/Khazaria (Ostolopovskoe, Zolotariovskoe settlements).
Wide spread of scales shows us the import of armors from East to West same as From South to North (the best example are type F armor scales fround in Bulgaria and.. in Birka).
This armour was found absolutelly undamaged and whole, long to the knee.
But sometimes we make it with separate skirt.
