So the Grau's secondaries are simmed as eighteen 120mm guns in six triple turrets - but if I remember correctly, the ship actually has twelve 120mm guns in six twin turrets. The spare gun in each turret was simmed in as a way of showing that there was some extra play in the design for, say, extra automation equipment etc.
I think Grau is the only case of that happening to a Peruvian ship, but there are others elsewhere in WW...

Okay - but in the original sim I do not find an reference to miscellaneous weight set aside to reflect that. Most of the misc weight pertained to the aviation facilities, and I had to play with those to find enough for the electronics. Has it been an oversight from day one?
Quoted
Secondary armament = 3 X HA/LA twin turrets on each beam.
Torpedoes are mounted in 2 quad turrets, 1 to each beam

Basically, to fix it, just re-sim the ship with 12x120mm secondaries in 6x2 configuration, and then add in the miscellaneous weight you'd gain.

So the commentary is there. The guns are twins, but they've been simmed as triple mounts...
