Thought I would share more at this point as I'm running out of content for the blog. Found in the same thread as the previous one.
What I know or guess: these are the generation of warships before the pre-dreadnoughts and after the ironclads with side-batteries used at, for example, Lissa; they still have cannons in the old ship of the line style and turrets on deck and on the sides.
Only info I've got is this one's name. Must have been pretty temporal, seeing that I haven't stumbled to these kind of ships yet - correct me if I'm wrong.
