The picture is of an improvised armoured car, I don’t know if the car is made in Spain but the armour and guns where attached by the CNT-FAI. They also constructed armoured cars under Soviet direction with soviet plans in Valencia, the UNL-35, and the AAC-1937 (sometimes known as the Chevrolet 6×4). So not exactly tanks but they did make armoured vehicles.
