The hulls look great. Not meaning to be critical but the bridge structures on Massena seem a little short. The Armored Conning tower is 6" and the wheel house above it is 6.5". I don't have the actual dimensions but I've been aboard a few old ships including USS Olympia. On Olympia the main deck was 6.5" to the botton of the joists (one foot thick ) and 7.5 feet to the botton of the next deck. Inside the armored conning tower was not quite 6.5" (the vision slits were about 5.5" high). The wooden wheel house was just under 7.5 feet. Nice & roomy so the captain didn't knock off his hat. Please take this as a suggestion. Otherwise your stuff is super and I am very impressed by the amount of work involved.
Hello
I've checked the size of the bridge and CT with the builder's plans (which are admittedly rather blurry and contain lots of lines which are probably necessary to build the ship but more of a hindrance when trying to draw it) and it seems right. Maybe french officers were shorter than american ones
