The background for the recently released Turkish Sultan Selim battlecruiser mentioned its German roots, and how the Turks converted it and then built more of the same design.
So what if we go back to the original Teutonic battlecruiser, replace the round turrets with more Germanic square ones ? Hey presto, we get the SMS Goeben (which is the name of one of the real Moltke class battlecruisers that the Germans transferred to the Ottoman Empire in August 1914). It’s exactly the same model as the Sultan Selim, just with German turrets instead (the turret pins on the round turrets are slightly larger so you’ll need a steady hand to centre the German turrets on the rings, and the rearmost turret is a very tight squeeze against the superstructure).
