Yes, 3940s, as the French often applied red paint to their ships.
My English ships are 5135s.
These are what I'm using for my French and British flagships too!
I like your French Captains. Right now I'm debating what kind of legs to use for my French and British captains. I'm leaning toward the breeches with stockings you've chosen, as they're more historically accurate, but I personally like boots or trousers better.
