Polish Błyskawica [*Lightning* in Polish] Submachinegun.
The Israelis also turned out many copies of the Mark II Sten during their War for Independence from the British, close enough copies that most parts interchange.
Sten guns were engineered to be “assembled in any garage.”
WW II resistance fighters in some places (like Denmark) made their own submachine guns. Still amazes me gubbermint folk think they control machines, and the people who run them.
