MFR Model 40 (PzB 40 W)
the beginning of World War II armed infantry units of the German army were anti-tank guns (MFR) PzB PzB 38 and 39 armor penetration of up to 30 mm. However, the creation of new tanks and increased thickness of the armor showed the ineffectiveness of anti-tank weapons.
In this regard, in 1940 were big competitive tests of new samples of the German anti-tank rifles, which were intended to replace singly PzB PzB 38 and 39. Then the German designers have offered a number of experienced self-loading rifles with elevated anti-martial and performance, designed for use of a standard 7.92-mm cartridge «Patrone 318" (metric designation 7.92x94) with armor-piercing bullet SmK and armor-Tracing-chemical SmKHRs-L . Spur. Tactical and technical characteristics of the presented prototypes PTR despite a strong variation in the designs were very similar. This was due to very strict conditions for the job. To test the samples included the following anti-tank guns models: 40, 41, 42, 43 and 44.
antitank rifle «Model 40", to get the index «PzB 40 W», was created by the designers of the company «Carl Walther GmbH» together with the firm «Merz Werke» in Frankfurt am Main.
feature of this self-loading rifle was the widespread use of stamping parts for the manufacture of the majority.
