Humber Mk III/IV
with III and IV gun variants
The Humber Mk III shared the same hull as the Mk II, but was fitted with a new redesigned 3-man turret, to replace the old 2-man turret of the Mk I and II. It retained the same armament as the Mk II, a .303" machine-gun and a 15mm heavy machine-gun.
Though it was intended to allow 3 crew in the turret, with its full compliment of crew it still remained cramped. In practice many Humber Mk III crews simply retain the two men in the turret as they had with the Mk I and II, but with more room and in relative comfort. The extra room allowing them to operate more efficiently.
