The SS sim has the 6" and 75mm guns in hull casemates, but your picture has the 6" in the superstructure and I don't see the 75mm at all.

The mix of gun sizes is a little odd: the 21cm guns and the 6" guns really don't go together, a German-built vessel would have 21cm and 15cm (and 8.8cm) guns where a British built vessel would have 7.5", 8", or 9.2" guns, 6" guns and 3" guns, and an American-built vessel would have 8", 6", and 3" guns.

It is a very interesting thing that the 305mm gun and 152mm QF gun are from france , Only 210mm gun is from Deutsch. 75mm Anti-torpedo gun is builded by owner of oneself.



en, 6"and 75mm guns is settled at a error location.

75mmguns is too little to not drawing.


I should modify it at next time.

In the period given, France produced 138.6mm and 164.7mm guns, for the purposes, the 138.6mm is probably a better choice.

I used the following link.

6" is 'FR RU 6in 15cm 45cal 1892' by canet

The link is from "http://navalhistory.flixco.info/H/208018x53535/8330/a0.htm"

12" is 'FR 12in 30cm 40cal 1896 '
