Straussler V-4 Hungarian light tank of WWII period. Developed by Nicholas (Miklós) Straussler, Hungarian -born English designer in cooperation with the Hungarian Weiss Manfréd firm for a tender by the British Army. Two prototype chassis were made in 1936, one for the British Army, and another one secretly for the Royal Hungarian Army. After the trials, the Hungarian V-3 chassis recieved a provisional turret and the concept was further developed to the V-4. The V4 had a cross-articulated three-point suspension with leaf springs and rubber bogie rollers.
