The links you cite don't support the argument that Germany had NO gun control. Taking everything in the wikipedia article at face value, tt says that the the 1928 law relaxed restrictions, but it required various separate permits. Let's see. You have a corrupt dictatorship and are required to obtain various permits to possess a gun. I can only imagine who the government allows to possess firearms: those that openly support the government. It is also interesting that it was explicitly forbidden for Jews to possess firearms. I wouldn't call that NO gun control without even going to the actual details of the German laws.
