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.
During the invasion of france in 1940, it started to show it's limitations when it went up against the better armored French and British tanks.
By 1941 there were 15,000 produced.
Once the Pak 35/36 met the T-34/76 in Russia in 1941, it was completely obsolete. Some attempts to use stick bombs, to extend it's life, that went over the muzzle weren't at all useful in combat.
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.
