Here are my WIP M4A3's - there's a third under construction, but I've run out of bits and have to source some more. Both these models have additional stowage, because to me a US tank never looks right unless it's heavily stowed. The stowage is from a variety of sources (mostly Tamiya and Warlord). The 76mm turret was modified a fair bit to make it look more accurate. The machine guns are from the Warlord M3A1; the .50cal is rather eccentric in terms of detail, but looks more in scale with the chunky Warlord minis.
