These were done for a wargamer who traded me some other Minifigs Napoleonics for them. We discussed the uniforms at some length, following these references:
The owner planned these to serve as the 2nd and 3rd regiments of Silesian Landwehr. The Mont Saint Jean site indicates that the 3rd Regiment perhaps should be in the schirmutze (peaked cap) that only the officers and drummer are wearing. So in case he needs to be able to distinguish between regiments, I painted twelve figures with white shoulder straps (indicating a 1st Battalion) and twelve with red (2nd Battalion); I did not attempt to paint regimental numbers on the shoulder straps!
