Pak is short for Panzerabwehrkanone.
Rheinmetall started to design an anti-tank gun for the army in 1925 and started to produce it in 1928. At the time it was a very advanced design as the German army was still primarily horse drawn.
It had a sloped shield, round split-trail legs, and a long barrel.
Production was accelerated in 1934 after the NSDAP came to power. Starting in 1934 the wheels were solid and had pneumatic tires.
Some were sent to Spain in 1936 and fought in the Spanish Civil War. It was well liked and could handle most of the armor that saw action.
By 1941 there were 15,000 produced.
It was copied by the Japanese and designated the Type 97. Italy received some and designated them the Cannone contracarro da 37/45. The Netherlands called them the 37-mm Rheinmetall. Russia called them the M30.
