Or perhaps this? Ironclads are kind of tricky when you are use to more modern vessels. One wonders what the above deck armored gunhouse would be considered "upper armor" and wether in this can the raised quarterdeck would be "end armor" or "the control tower"
This is rough still, but it gives a general impression of the vessels design.
