Alright.. Here we go again.
This is a pre-dreadnought built by Newport News in 1896 for the Denton Navy. It was designed in conjunction with the Kearsarge BB-5 and Illinois BB-7 battleships being built at the time, so it looks a lot like both ships. The layout follows the Illinois, when it comes to the gun setup, except for the addition of another set of 5" casemates amidships.
Now, I did do this fairly quick, so if you spot anything I missed, just let me know and I will fix it!
Here she is, DNS Innsbruck.
