As part of my Sikh War project I needed a unit of native cavalry as Governor General’ Sir Henry Hardinges body guard. Naturally enough they had a fancy uniform and no one makes them in15mm. I converted some Irregular Miniatures Native Cavalry. It was not a big job but it was a little tricky, as 15m helmet cords and plumes would be. They came out ok.
If you are interested in the Sikh Wars you can see more of them and a 15mm Sir Henry on my bog.
