I would like to build a diorama based on the famous painting by Horace Vernet. As a starting point I would like to know if any model maker has any figure available in the painting besides Napoleon holding the periscope and the chasseur a cheval de la Garde. I am particularly interested in the ADC handling the map to the mounted Napoleon and the guy wearing a white pelisse and gold embroidered red hussar type shako and red overall and mounted on a dappled grey horse. Any help on experts in Napoleonic period in this forum is highly appreciated. My preference in the scale is 54mm and upwards.
