Ah, the perils of research!
I can’t find my original source for the sky blue coats for French infantry in 1914.
But now it seems clear that they were not available until 1915 at the earliest. So do I try to repaint the coats (probably sleeves and skirts only at this scale) or ignore it on the basis that these soldiers spend most of their little tin lives in an alternative history setting?
I have decided. To get the next game out of the way I will use them as they are, and then try to get them in their correct coats before the next battle. They are, after all, currently still in 1902. If they make it to 1915 they can have their old coats back. I am trying to resist buying more lead and starting afresh. I have already used half of next month’s wargaming budget.
