UM MT 605 Soviet 45mm Anti-Tank Gun 19-K (1932) and 76mm Regimental Gun OB-25(1943)

19-K wz.1932 is a Soviet 45 mm anti-tank gun from the interwar period and World War II. The first prototypes of the weapon appeared in 1931, and serial production continued in 1932-1937. The weight of the weapon was up to 425 kilograms. The initial velocity of the shell from this gun was up to 750 m / s. The 19-K wz.1932 gun was created to supplement and then replace in the line of the Red Army the 37 mm 1-K wz.1930 anti-tank gun, which was produced under license from Rheinmetall concern. The new gun was based on its predecessor, and most of all it used its handguard, but with a new barrel with a larger diameter. The new gun was generally a good weapon, but it was replaced relatively quickly by the new 45mm - 53-K wz.1937 anti-tank gun. The 19-K wz.1932 guns were used in combat in Poland in September 1939, in Finland during the Winter War of 1939-1940 and in the initial period of the German-Soviet war in 1941-1945.
