The Flakpanzer IV Wirbelwind, or "Whirlwind", is a German self-propelled anti-
aircraft gun from the end of World War II. It was built on the chassis of the
most popular tank of the Third Reich The Panzer IV. Production began in
November of 1944. The chassis of the older Panzer IV or newer versions,
withdrawn from the front for repairs, were rebuilt. The traditional turret was
replaced by a polygonal open turret equipped with a 20mm Flak 38 quadruple
anti-aircraft gun. The rotating turret turned out to be very effective in the
fight against the infantry. Due to the dramatic situation of the Third Reich,
the production of this weapon was limited to only 87-105 copies. The
Flakpanzer IV Wirbelwind is faithfully reproduced by COBI using 585 blocks and
all graphics on the vehicle are pad printed directly on the blocks. The set
also includes two figurines of German soldiers. The shooter is equipped with
binoculars. The Luftwaffe footman is equipped with a Mauser rifle. Many
movable elements, such as the tank turret, barrels, rotating wheels and tracks
as well as tilting service flaps hiding the engine dummy.
