Contemporary "Augsburger uniform or Series" covering 1802-1810. Almost every nation of the time was represented with at least one sheet, which was usually 5 per nation, including 2 each for the infantry and cavalry (often divided into light and heavy forces) and 1 for the artillery. Amongst these amazing plates are very interesting illustrations of Ottoman troops & Cossacks. link
