I found a very funny text on the Internet. Its name was "How was the British Fleet planned for ages". However, the author is unknown. Original text is on Russian, but I think it worth be here on this site. I tried to translate it. ---- 1st Sea Lord (timidly): Guys, why don't we build a new battleshi...
It supposed to be the additional armor plates added during a refit. Also I just used to draw those weld lines on every my dreadnought because the belt looked plain and poor for me without them. But I desided not to do this anymore, cuz it looks too senseless.
I will edit the mainmast soon, thanks.
