The Crossley IGA3 armoured car was built from 1928 on a modified version of the IGL3 chassis. Early versions seem to have used the 25/30 4.5 litre four cylinder engine but in 1930 the larger 38/110 6.7 litre six cylinder petrol engine was being offered.
The completed chassis were sent to Vickers to have the superstructure and armament fitted. Customers included the British army, RAF and 14 were supplied to the Iraq military.
Chassis numbers were in either the 306xx range.
IGA3 with wireless equipment.
Two of the three IGA3s supplied to the RAF. The third example had the dome type turret that can be seen on the second car.
