German 2 cm Flakvierling 38

This is the second part for my Bachelor Project.

The Flak 38 was a 20 mm anti-aircraft gun used by various German forces throughout World War II. It was not only the primary German light anti-aircraft gun, but by far the most numerously produced German artillery piece throughout the war.
It was produced in a variety of models, notably the Flakvierling 38 which combined four Flak 38 autocannons, which could fire 220 RPM.
