ACV India pattern Mk.II
With the inability of Britain to supply Commonwealth forces with armoured vehicles early in WWII, India started production of amoured cars based on imported chassis.
The initial Armoured Carrier, Wheeled, India pattern Mk.I was based on a Ford chassis with a front mounted engine. However this was dropped for the definitive model with a different Ford chassis with a rear mounted engine, abbreviated to ACV India pattern Mk.II (I can't find a definition, but I assume the "V" was changed out for Vehicle). Production was split between Indian Railways and Tata, with the Tata built machines being refered to as Tatanagars.
In service they could be fitted with either a bren machine gun, or a Boys anti-tank rifle. They were deployed with Indian troops throughout the Middle East and North Africa, and were delivered to Malaya and Singapore before the start of the Pacific War where they were also used by British, Australian and Dutch forces.
New Zealand also built vehicles, with the ponderous name of Armoured Carrier, Wheeled, India pattern Mk.II, New Zealand pattern - abbreviated to a more manageable ACV-IP 2 New Zealand pattern. The NZ vehicles were deployed during the Korean War as Local Pattern Observation Posts (LPOPs) artillery observation vehicles. They were withdrawn from service in 1956.
