If it is a reissue of the old Monogram Hedgehog kit (sandbar armor and Cullin hedgerow cutter), it is a radial engined M4 direct vision hull with small hatches, 3-piece transmission cover, 75mm low bustle turret (no loader's hatch), narrow gun rotor, and early M3 style bogies.
Basically, it is a very early M4 and I'm not even sure if a version with such early features would have been in service beyond North Africa let alone with the features that place the tank in Normandy after D-Day (like the sandbag armor and hedgerow cutter). But I'm no Sherman expert so take my statement with a grain of salt.
The basic kit (less the sandbag armor and cutter) has the features of the original M4 as it came off the assembly line before any combat testing and modifications made to the production line.
