i've done that for fun two days ago after completing the Nagato class but i left it unfinished untill now, i've made a quick fix this evening by adjusting the riggins and put the catapult with is plane.
Basically i'ts just a kitbash of my 1937 IJN Mutsu onto Midnightnova's 1925 IJN Amagi, do not take it too seriously; let's say it's a sort of christmas present for IJN lovers
