From Kalashnikov's CVKalashnikov did work on the state railways before the war, if I'm not mistaken, so he apparently had at least some engineering experience and knowhow.
Translation:Till 1936 Michael Kalashnikov go to school. Upon termination of 9-th class it has gone to work the technical secretary of a political department of 3-rd branch of the Turkmenian-Siberian railway.До 1936 года Михаил Калашников учился в школе. По окончании 9-го класса он поступил на работу техническим секретарем политотдела 3-го отделения Туркестано-Сибирской железной дороги
So here I can not see engineering experience and knowhow

I see propaganda experience

But here I can not see problem.For you designer of АК-47 Kalashnikov for me Hugo Shmaysser it depend on how man resistant to propaganda and faculty to analysis.A lot of people admired ideals of nazi and rednazi some not.So I have the advantage over you I lived in USSR and I can read in russian
and I know how act evil state propaganda.Sometimes I am visiting russians web forums and there russians colleagues fully proved for me that Kalashnikov are only clown of propaganda
Here good example how evil state acted and act against germany inventor
