HMS Colossus 1879

[Carthaginian]

*raises hand*
Question:
How do you have six 6" guns in four mounts on the BB1878? Also, are these breastwork monitors? The latter ship seems to simply be a Trafalgar class turret ship, built about decade early. Colossus herself had her turrets 'On Side, All Amidships' in Springsharp.
