M4 Sherman Composite hull
Manufacturer: Hat M4 and ESCI M4A1 kit bash
Parts from Hat M4: 1. Gun and mantlet; 2. Rear top hull; 3. Lower hull and wheels
Parts from ESCI M4A1: 1. Turret; 2. Differential cover; 3. Front hull (cast); 4. Figure (un-stiffened)
This is one way to "correct" the ESCI/Italeri M4A1. Another way is back date the hull with small narrow hatches. When Hat releases the M4A3 model, there will be even more possibilities.
