RB-Model 35B79 Lufa 75 mm & 47 mm & 7.5 mm MG Char B1 bis

The ABS SA37 is a French 75 mm howitzer from the interwar period and World War II. The weapon was the main armament of the Char B1 bis heavy tank. The presented weapon had a barrel length of 17.1 calibres, i.e. 128.25 centimeters, and was devoid of a muzzle brake. The howitzer was intended primarily for infantry support, and therefore it was intended primarily for firing high-impact and fragmentation projectiles. However, it was able to fire APHE (anti-tank) missiles. Armor Piercing High Explosive ), more precisely - the Obus de rupture Modele 1910M missile, which could have been lethal to all German light tanks from the 1939-1940 period. However, this hit would be difficult, because the ABS SA37 howitzer was placed in the Char B1 bis tank, and its targeting required the maneuvering of the entire tank. In addition, the fire unit of this gun at the Char B1 bis was 74 shells, of which - most often - 5 to 7 were APHE shells.

The SA 35 mle 1935 is a French 47mm tank gun from the interwar period and World War II. The weapon was the armament of the Char B1 bis heavy tank and the main armament of the Somua S-35 tank. The plants were responsible for the development and production of weapons Atelier de Puteaux (APX for short). The presented weapon had a barrel length of 50 calibers, i.e. 235 centimeters, and was devoid of a muzzle brake. The theoretical maximum rate of fire was 15-18 rounds per minute. However, due to the tightness of the Char B1 bis turret, it was only wishful thinking. The initial velocity of the projectile fired from this weapon was up to approx. 850 m / s, and the effective shot range did not exceed 2000 meters. The gun SA 35 mle 1935 was a modified development version of the 47 mm APX towed anti-tank (anti-tank) gun. It is assumed that the SA 35 mle 1935 (similarly to its towed prototype) was able to overcome an armor plate inclined at an angle of 90 degrees with a thickness of 60 mm from 550 meters, which allowed to fight it at this distance almost every German tank from 1939-1940 .
