Although greatly restricted by the Treaty of Versailles, the Kriegsmarine could invest and production of new, improved weapons systems for the warships that they
could construct. Germany recognized the importance of effective anti-aircraft guns. At a time when the Royal Navy and the United States Navy were satisfied with
.50 caliber machine guns as the primary light anti-aircraft gun, the Kriegsmarine went farther and developed the best 20mm gun of the time. It was the 20mm Flak
C/30, which fired a heavy and powerful shell. The C30 was fired from twenty round magazines and had a cyclic rate of fire of 120 rounds per minute. However, the
C30 was unsatisfactory on two points. The rate of fire was slow and even with the slow rate, the 20 round magazine was quickly depleted and resulted in frequent
magazine replenishment. The firm of Rheinmetall further refined the C30 design to address these issues and produced the C38 gun. The C38 gun was lighter than the
C30 gun and had a rate of fire of 220 rounds per minute. The German word Flakvierling stands for quadruplet anti-aircraft gun. Although there were single gun 20mm
mounts, the quadruple 20mm gun mount C38 was more common from 1940 to 1945. The Flakvierling C38 could be found with and without gun shields and was
used by the Kriegsmarine and Wehrmacht.

If you have a 1:700 scale model of
Tirpitz, Scharnhorst, Gneisenau, or almost any ship of the Kriegsmarine, take a look at the plastic parts for the Flakvierling.
Injected plastic molds inherently can not replicate the thin barrels required for scale light anti-aircraft guns. It is true with the allied Oerlikons, Japanese 25mm guns  
and certainly true with the German Flakvierling.
3D Model Parts has produced the Flakvierling C38 with gun shield and with 3D Model Parts set D704 you get eight
extraordinarily fine resin miniatures of the Flakvierling C38. Each gun mount comes with two pieces, the 4-barrel gun block and the mount. Both parts are loaded with
minute detail that is far superior to any injected plastic part of this weapons system. Look at the comparison photographs and you will see what I mean. You can not
go wrong with this weapons set.
