The M3 and M3 Lee Medium Tanks (Patreon)

A good view of the different turrets used on the M3 Grant and M3 Lee Medium tanks. The Grant, bringing up the rear, was modified for British requirements. The small machine gun turret was removed and the turret bustle extended to accommodate the radio.
The convoy is passing the Weld Arms, just a few miles from us here at Bovington. They're most likely heading towards the Gunnery School at nearby Lulworth Camp.
