PTR BSW Model 1
In 1940, in order to replace in service with the Wehrmacht singly antitank guns (MFR) PzB 38 and 39 chambered PzB «Patrone 318" (metric designation 7.92x94), announced a competition to create new models of self-loading anti-tank rifles. German designers have developed a number of experienced self-loading rifles with elevated anti-martial and performance, designed for use cartridge «Patrone 318." Different armories firms were represented antitank rifles Model 40 (PzB 40 W), Model 41 (PzB 40 M), Model 42 (PzB 40 G), Model 43 (PzB 40 K) and the Model 44, the tactical and technical characteristics of which, despite the strong variation in the designs were very similar.

In October 1940, took careful multilateral test new anti-tank rifles. However, by the beginning of these tests the fall of 1940, some of the firms, based on the experience of the French campaign, where German infantry tanks met with armor up to 60-70 mm, have already begun to study the establishment of a new, more powerful weapons, which would be able to resist promising armored opponent. In this regard, the program to create automatic anti-tank weapons under the 7.92-mm cartridge 318 was closed as unpromising, and a representative sample of the guns remained in experimental models. Designers were invited to begin work on a more powerful anti-tank guns.
the fall of 1941, based on a new assignment for designing large-caliber anti-tank rifle PzB 243, there is a number of prototypes of German MFR, which used quite effective 15h96 mm bullets from a high-caliber machine gun MG 151 aircraft. Participated in the competition design teams firms Gustloff, Krieghoff, Berlin-Suhler Waffen und Fahrzeugwerke (BSW) and SS-Waffenakademie.
company BSW presented singly prototype 15-mm anti-tank rifle, get the index «BSW Model 1».
This gun is an enlarged version of the MFR in size RzV 38, but calculated under the cartridge of caliber 15 mm.
Like RzV PTR 38 rifle BSW Model 1 refers to the single-shot with the mechanical action of the barrel recoil when fired.
recoil device consisted of a helical spring, is worn on the trunk.
trunk enclosure, manufactured by stamping.
also to reduce recoil barrel equipped with a powerful muzzle brake.
bore is locked by a semi-automatic vertical wedges. Reloading shutter trigger lever, made in the form of the pistol grip fire control.
hammer type firing mechanism.
safety mechanism consisted of two safety devices: first - lever type was mounted on the right side of the receiver, the second - included Pivoted butt down, which in turn reduces the size of the weapon in the stowed position.

In the stowed position
To reduce the size
guns stowed and stability when firing the weapon was equipped with folding bipod.
At sufficiently powerful cartridge the gun turned out quite compact and light. At a mass of 15 kg anti-tank gun BSW Model 1 had a total length of 1430 mm, and the length of the barrel-838mm.
However, the emergence in the early 1940s, powerful tanks made unnecessary work to create large-MFI as traditional means of infantry anti-tank defenses were underpowered and have not fully met the requirements of the time. By the end of 1941 abroad opportunities in 60-70 mm armor penetration at ranges up to 100 m, made by German anti-tank guns, with constant capacity striking power armored troops in the armies of the anti-Hitler coalition, leaving virtually unarmed Wehrmacht infantry in close combat, but German antitank artillery escorts also not kept pace with developments in the front. Therefore, all work to create a 15-mm anti-tank weapons were terminated and they remained embodied only in test samples.
