Trumpeter 02347 German 37mm FlaK 43 Zwilling 1/35

The 3.7 cm Flak 43 was a dramatic improvement over the older models. A new gas-operated breech improved the practical firing rate to 150 RPM, while at the same time dropping in weight to 1.250 kg in combat, and mere 2.000 kg in transport.

The barrel was shortened to 89 calibers. It was also produced in a twin-gun mount, the 3.7 cm FlaK Zwilling 43, although this version was considered somewhat unwieldy and top-heavy. Large-scale production did not start until 1944 and about 7,216 were produced by end of the war (Zwillings included, each counted as two guns).
