Imperial Chinese Fleet

[Walter]

Well, Dupuy de Lome was the first cruiser I simmed of the lot. Not sure what the Fench were drinking when they came up with the 193mm caliber (must have been the wine), so I rounded it up to 200mm.

[Walter]

I will admit that I had forgotten to take a look at the guns table when I simmed it (didn't know it went that far down) so I will correct the 200mm guns to 40 cals.
