Hello again!
To inflict my french collection in its entirety upon you all, here are some fictional designs. I thought them up many years ago for a self-made boardgame loosely based upon the 1970s vintage
Wooden ships and Iron men, with a similar game mechanic to recreate World War I battles. It went through five different editions under the working title
Iron ships and Wooden heads and never progressed beyond the playtesting stage because it just did not work properly. What remained were some ship statistics I made up for the French, Russian and US Navies to equip them as fully and diversely with battlecruisers, light cruisers and destroyers as the German and British navies were.
First, a very early french battlecruiser design, basically a much enlargened Edgar Quinet:
