The 7.5cm Pak 41 was produced by Rheinmetall and was one of the last anti tank gunss produced by Germany during WWII. It was utilised the squeeze bore principle with it's barrel split into three distinct sections. The rear section was straight and rifled. The middle section was unrifled and tapered while the muzzle end was sgain straight but unrifled. This narrowing of the barrel produced a higher muzzle velocity making the Pak 41 capable of firing a 7.5cm shell at 1,200m/second.
