I too love these little coastal defense baby battleships. Many being from Scandinavian countries. I look forward to following this build!
While I hadn't looked, the only ship of this class in paper I have known about up to this point is the Peder Skram from Paper Shipwright.
Peder Skram – Paper Shipwright I've more than once thought about ordering one put also know I tend to struggle with finishing more complicated models... Once of these days maybe...
