Early Qing Armor 镶铠甲
Here's several historically accurate Qing brigandine armors.
In the early years of the ethnically Manchu Qing Dynasty (1644- 1912) most of the fighting were done by the traditional Banner Armies. These armies relied mostly on mounted archers and disciplined infantry blocks composed of arqubusiers and spearmen.
These musketeers most likely belong to the Plain Red Banner Army or the Bordered Red Banner Army. They are equipped with brigandine armor with horse hair tasseled helmets and a mirror breastplate (the officers have dragon insignia on their chests)
The cavalry are equipped similarly, since the end of the Ming dynasty, horses are no longer equipped with their own armor. This is the heaviest cavalries are going to be armored, although their role gradually declined throughout the dynasty, cavalries in general still are widely fielded all the way until the end of the Chinese Civil War in 1949.
The Eight Banners consisted of three principal ethnic components: the Manchu, the Han, and the Mongols, The first Chinese additions were merely sprinkled into existing banners as replacements. Eventually, the sheer numbers of Chinese soldiers caused Manchu leaders to form them into the "Old Han Army" (舊漢軍, jiù hànjūn), mainly for infantry support. In 1631, a separate Chinese artillery corps was formed. Four Chinese banners were created in 1639 and finally the full eight were established in 1642.
From the time China was brought under the rule of the Qing dynasty (1644 – 1683), the banner soldiers became more professional and bureaucratized. Once the Manchus took over governing, they could no longer satisfy the material needs of soldiers by garnishing and distributing booty; instead, a salary system was instituted, ranks standardized, and the Eight Banners became a sort of hereditary military caste, though with a strong ethnic inflection. Banner soldiers took up permanent positions, either as defenders of the capital, Beijing, where roughly half of them lived with their families, or in the provinces, where some eighteen garrisons were established. The largest banner garrisons throughout most of the Qing dynasty were atBeijing, followed by Xi'an and Hangzhou. Sizable banner populations were also placed in Manchuria and at strategic points along the Great Wall, the Yangtze River and Grand Canal.
