In April of 1943, a better, more modern design was submitted. This tank was armed with the 75 mm 43M tank gun which was a hungarian development of the German 7.5 cm Pak 40. The Hungarian version differed considerably to its German counterpart, and could fire either German PaK ammunition, or special Hungarian ammo. This model was designated 43M Turan III. It mounted the 75mm gun in a modified turret and had thicker armor, but was otherwise similar to previous Turán I and II.
