Embrasure

Frontal wall of the pillbox has the antisplinter armour covering. The chill cast iron embrasure casting turn the scale at one half ton. The semiautomatic 45-mm antitank artillery system with  duplex 7.62 machinegun was mounted on the pins of embrasure. The toothing guide for horizontal moving of the gun is seen on the picture. The sector of fire was 45°.
