Talk:20.3cm (No.3) Twin Gun Mount/@comment-26478697-20160113120411/@comment-26478697-20160113130806

Chinese wiki. It said that because when the pacific war started most of the heavy cruisers already equiped with the 20.3cm(no.2) guns historically but in game 20.3cm(no.3) guns appear eariler than no.2 guns that's probably why default 20.3cm guns have the night battle accuracy bonus instead of the no.2 guns and to compensate the difference, no.2 guns give +1 to accuracy.

Here's the sauce if you can read chinese: http://zh.moegirl.org/%E8%88%B0%E9%98%9FCollection:20.3cm%E7%82%AE#20.3cm.283.E5.8F.B7.29.E8.BF.9E.E8.A3.85.E7.82.AE
