An interesting model of the 1950s with the so-called "swinging" tower is on the photo. It's gun is fixed tightly in the tower, and the upper part of the tower swings in a vertical plane on the trunnion. This construction allows to make a loading of weapons by type of semi-automatic and excluded loader from the crew. Tanks of this type took Latrun fort in 1967. Tank is armed with rather good 75 mm cannon, developed on the basis of the German KwK42 L/70 from "Panther" tank.
