75 mm Pak 40 captured in Tunisia:
United States Army in World War II, Pictorial Record, The War Against Germany and Italy: Mediterranean and Adjacent Areas, 1951, pg 63
In 1939 the Germans decided that they were going to need a more powerful gun than the 5-cm Pak 38 to go against newer Soviet tanks. Rheinmetall-Borsig were asked to develop the new design. Basically Rheinmetall upscaled the 5-cm Pak 38.
It was adopted in 1940, but production didn't reach the troops until late 1941.
In anticipation of shortages of light alloys, the Pak 40 was designed primarily out of steel. The shield was made from flat plates.
The 7.5 cm gun was placed on a 10.5 cm howitzer carriage to be used as a light artillery piece. Some formations were using this weapon in 1945.
FK stood for Feldkanone or field gun.
