Humber Mk IV Armoured Car

The Humber was one of the most widely produced British Armoured cars of WWII. The Mk I was armed with one 15mm BESA and one 7.92mm BESA machine gun. The Mk IV saw the 15mm BESA replaced with a 37mm M5 or M6 gun around 1942. The larger gun required the removal of the fourth crew man (wireless operator) introduced with the Mk III and the turret hatches were redesigned with a new crew layout.
