Austrian Uhlans - I've painted up the 3rd Regiment to add to the existing 1st Regiment.
And the newly added 3rd Regiment with red Czapka, and falling plume rather than the upright plume of the first.
For completeness I'll add my comment from when I posted picture of the 1st Regiment - "the cords also had a very fine black hatching in real life, but given scale of figures and typical viewing difference (and consideration of my sanity!), I decided that trying to represent this detail effectively would be more time and trouble than it was worth."
There's also the 2nd regiment (green Czapka) and 4th regiment (white Czapka), but no plans to add those at the present time as this will be enough Austrian Uhlans for most scenarios I can imagine.
Next, Austrian Hussars, and many of them!
