A simple and ugly as sin looking model based on an interesting document from the CIA. In the year in 1953 in Leningrad and Novgorod oblasts (administrative division) certain soldiers were spotted by US CIA spies carrying yet unseen weapons, a new gas operated service rifle later to be known to them as the AK47. But as the said agents did not have the time nor the ability to examine the newly spotted weapon systems closely they had to instead rely on their sight and memory of the rifle when reporting about their finding back to the US. https://www.thefirearmblog.com/blog/wp-content/uploads/2018/03/CIA-First-Memory-Sketch-of-the-Kalashnikov-Rifle-2.jpg As the sketch was solely based on memory it looks really nothing at all like what the actual AK47 would have looked like, even the memorized sketch of the supposed cartridge that the AK47 would have fired was nearly completely wrong.
