Specific: Delivered by the
British forces in Germany in 1945. A total of 71 vehicles were
delivered. When the Humber Mk IV was demobbed in 1953, the inventory had
reduced to 64 units.
Historical: In 1939 existing facilities in
Britain were fully committed for the manufacture of
armoured cars. As the British Army was in a desperate need
for armour, the Rootes Group were asked to undertake the
design and production of a armoured car.
To save time,
Rootes adopted an existing design, the Guy armoured car,
and allied it to Karrier KT4 FAT which had been delivered to India
just before the outbreak of WW II. The first order for 500 units were
placed in 1940, and production by Karrier
began in early 1941.
Gradually improved in detail through Marks I - III. Mk IV
(from 1942) had a US M5 or M6 37 mm gun instead of the British 15 mm Besa.
When production resumed in 1945 around 3.650 units had been made, more
of half being the Mk IV version.
A Canadian version based on the Mk III, known as the Fox,
was produced by General Motors and Hamilton Bridge. Some
200 vehicles were made.
