Well, forgive me but I am a serious Francophile - the current units DO wear a shako, but a British-pattern model. Which is great for them and also for several other uniforms of the period.
But I must find a way to have troops with the French pattern shako (or more correctly, the Hungarian shako), that was also used by the Prussians and Russians of the time.
And then a real Cuirassier skin, and then a Hussar skin with a real busby and pelisse.
What I really need to do is learn to change the models and skins myself. I have all the tools downloaded and have been playing with them a bit. I need to find more time for this. Don't we all need more time!
Thanks for your help, any tidbit of info is much appreciated.
