5 cm Pak 38

The 5 cm Pak 38 (L/60) (5 cm Panzerabwehrkanone 38 (L/60)) was a German anti-tank gun of 50 mm calibre. It was developed in 1938 by Rheinmetall-Borsig AG as a successor to the 3.7 cm Pak 36, and was in turn followed by the 7.5 cm Pak 40. The unique curved gun-shield design differed from most WWII anti-tank guns which had either one flat or two angled and one flat gun-shield plates for ease of manufacturing.
