This large 4 wheeled armoured car had limited cross country capability based as it was on an Ursus truck chassis. The vehicle was armed with a 37mm SA-18 Puteaux L/21 gun cannon and no less than three 7.92mm wz.25 machine guns (one for AA defence). Eight Wz29 armoured cars equipped the Mazowska cavalry brigade attached to the 11th infantry Division.
This curious "Dalek" like armoured car was mainly armed with a single 7.92mm wz.25 machine gun though some versions mounted a 37mm SA-18 cannon. Thirteen Wz 34's were used to equip the scout car company attached to each Polish infantry division.
