El Taller produces great mounted figures. Perhaps in a similar manner to Henkm cutting either the foil provided or using the foil from wine bottles, (though less likely to get foil these days) can be difficult to get the reins fine enough. However, I once bought pre cut reins, cannot remember them manufacturer, but they just curled up when you cut them out off the frame holding them, so back to foil.
Hope El Taller finds a British supplier soon.
Once I get through my current batch of figures, could be tempted to get King George V and place him with some of his Indian Army soldiers.
