Worth pointing out in the design of the AK47 that it was based on the earlier work of Hugo Schmeisser.
Not just that Mikhail Kalashnikov took inspiration from Schmisser but that he also had Schmisser working on the project as a prisoner of war. [0]
That doesn't mute any of the design discussions that were taken but it's worth remembering where the design came from.
