History

Originally designed for the Czechoslovak Army, some were also sold to Yugoslavia.

A number were appropriated by the Germans after the German occupation of Czechoslovakia in 1939 and used under the designations 3,7 cm PaK 37 (t). Captured Yugoslav guns were used under the designation of 3,7 cm Pak 156 (j).

Slovakia acquired 158 when it declared independence from Czechoslovakia in March 1939.^[2]

Design

The gun had a small shield and wooden-spoked wheels, although some were fitted with pneumatic wheels.
