There will be no Armored Trains at this time.
Way to lay down the law, Coach! :-D
But seriously, I do like your original concept, as it is ingeniously flexible, possible as a supplement for both periods. For sculpts I’m in general agreement. I like the idea of an “early war infantry” but am also conflicted, as this makes is a tad less applicable for ww2 (though the French did sometimes wear kepis even later… though mostly the officers…) I DO think though, that you should either do the Adrian helmet for both infantry and cavalry (making both more late-war in flavor) or for neither, making both more early war. (I’m not too worried about the French Cavalry’s applicability in WW2) For early-war French cavalry, you need one with the crested helmet (which incidently could serve for Austrian cavalry, too, which might make for an interesting item in the individual piece department, especially as Austrian cavalry didn’t necessarily have uniforms in the same color as their infantry, so you wouldn’t have to make the full French set in Austrian colors for us to use them this way, rather we could just let the Austrian cavalry be their stubbornly loath to modernize selves…)
Anyway, I’m torn about late vs. early war style uniforms for French infantry and cavalry, but think you should be consisten for at least these two pieces.
