The purpose of this process is to preserve the original state of the history object. As a result, I was able to stop the corrosion and preserve a lot of the original paint.

USSR - steel breastplates SN-42 began to arrive in the army in 1942 and were later used during World War II.The steel breastplates along with the conventional steel SSh-40 helmets equipped the assault engineers and demining brigades of the Supreme Command Reserve STAVKA, for which they are sometimes called "tubular infantry." Breastplate SN-42 was designed to protect against bayonet attacks, small fragments of shrapnel, and 9mm pistol bullets with lead cores, providing protection against fire from an MP-38/40 submachine gun from distances of 100–150m, and a single shot from a 7.92×57mm Mauser rifle (like the Gewehr 41), but on the condition that the bullet went on a tangent. Following the adoption of the Wehrmacht on the supply of 9mm cartridges, the cartridge code R.08 mE (German: mit Eisen Kern), with a bullet with mild steel (iron) core, required the thickness to be increased to 2.6 mm for the chest plate (2.5 - 2.7 mm). This redesign received the name SN-46.

No propaganda and extremism. Only history!
The demonstration of Nazi symbols in my videos is not propaganda of fascism, Nazism, etc. They are demonstrated exclusively for historical and scientific purposes.
