Trumpeter had two classes each in 1/350 and 1/700. 1942 and 1944.
The original in each scale were the 1942 Guadalcanal versions, which had the 1.1 machine guns. After 1942 they (the few remaining) had 20mm's added.
These in my opinion are the finest US cruiser kits ever produced. Of a class that was the backbone of the heavy gun ships for at least a year after Pearl Harbor.
The 1.1 guns are ok and replacements are worth the cost.
The 5" guns are well done, replacements are a clear upgrade.
They are great models.
