On the box:
Türk.[ische]-Leibgarde Ulan[en] - Lanciers turco.
Turkish Lifeguard-Uhlans.
19th century is not my field, so I can't tell if the figures/uniforms fit the box. Knötel: From 1890 Guard-Uhlans in dark blue with red facings. Tanzimat comes in mind.
On second thoughts, they might even be early 20th century.
