From a huge set of Napoleonic figures, these appear to be Battle Honors figures representing a Hungarian unit in the Austrian army. These were painted with a white base coat, a heavy black wash on top of that, and then, everything else in acrylics except for enamels on the weapons.
The figures are based for Napoleon’s Battles, probably the only attempt by the venerable Avalon Hill company to produce a set of miniature rules. The rules offer a hefty figure scale of 1 infantry figure equals 120 actual men. Even so, most people would find the enormous number of figures required to stage even one of the smaller historical scenarios a bit off putting.
