This gun was standard AA gun for larger German warships (Deutschland, Scharnhorst, Bismarck, "H", Admiral Hipper and Prinz Eugen classes).
Set of 16 pieces.

The set includes turned brass barrels. It is very simple to use in your model, and makes it extremely realistic. Simply cut off the original plastic barrel and drill a hole in the remaining part and insert the metal barrel using Cyanoacrylate adhesives.
