The Walther PP reviewed in the below video (through serial number documentation) was made in Germany during WWII in 1944 perhaps at the Walther Mfg. Plant at the Neuengamme Concentration Camp.
From the very first weeks of its existence to its liberation, Neuengamme was a deadly hell for the inmates. Despite the nearly nonexistent food rations, the inmates had to perform hard labor in all weather and under constant beatings of the SS guards. Very soon, the mortality rate reached an incredible level. Starvation, physical abuse, and total lack of hygiene and medical care very soon killed thousands of inmates.
During the war, tens of thousands of people were deported as concentration camp prisoners to Neuengamme from all over occupied Europe by the Nazis. In most cases they were incarcerated for having resisted German occupation, having refused to perform forced labor or simply as victims of racial persecution.
From 1942 on, the inmates were forced to work in the Nazi armament production. Initially the work was performed in the workshops of the camp but soon it was decided to transfer prisoners to the armaments factories located in the surroundings areas. One of the armament plants was Walther.
Because of the Allied advance, hundreds of inmates were also forced to dig antitank ditches. In many large north German cities, concentration camp prisoners cleared rubble and removed corpses in the wake of bombing raids.
Neuengamme Concentration Camp served the needs of the German war machine and also carried out exterminations through labor. The inmates (over 106,000) were spread over the main camp and approximately 80 subcamps across north Germany. At least 50,000 succumbed to the inhumane conditions in the camp.
Work at the mother camp was centered on the production of bricks. This included the construction of a canal to transport the bricks to and from the site. Inmates had to excavate the heavy, peaty soil with inadequate tools and regardless of weather conditions or their health state.
