I would love it if you could produce Napoleonic French Artillery in Great Coats, I don't believe they have been done in our scale or in plastic. In addition they could also be used for many allies of the French.
I hope you intend to produce these or other artillery sets as we are lacking choice in the range.
While I for one would support more Napoleonic artillery sets, I do wonder whether artillerymen in greatcoats 'works' other than on the march. Surely serving a gun with the physical activity involved would provoke gun crews to put their big coats aside while doing so, in all but the worst/coldest weather?
What would be useful in my humble opinion would be a set of French line artillery for 1812/13 to the end of the Napoleonic era, in campaign dress ie: trousers, jackets with minimal decorations, shakos with covers, with their muskets, greatcoats, packs stacked neatly to one side.
