Thanks all. I shall proceed with the Brunswick Uhlans!
Unfortunately, I may have to add plumes, but if that’s all, then not too bad. Now for what to do with those Brunswick Hussars 😁
Napoleonic Hussars pretty much wore the same style uniforms in all of the nations armies only head gear was sometimes different, so my suggestion would be remove Brunswick Hussars heads and replace with 1805 Russian Line Infantry heads thin or replace plumes and you have Austrian Hussars.
