Superstructure files for the type 1936 destroyers. The type 1936a destroyers also used a very similar superstructure, so you can probably use these files.
There are a couple of variations included. First is a different middle superstructure where I fudged the deck house and AA platforms to allow you to hide a pump motor that sticks through the deck. Second is a removable aft superstructure that allows you to install a gun easier.
