Hey David she is a bit of a mish mash, and I'd have to disagree say that the bogey housings contain the upswept late style return roller arms as found (mistakenly) in the Tamiya M4 kit, and in all 76mm equipped Sherman kits and M4A3(75)W kits. The late style dished wheel can be found in the Tamiya M4A3(75)W frontline breakthrough kit.
The transmission housing cover appears to be the earliest of the one piece cast types with a well rounded front. It appears to have applique cheek armour which in conventional wisdom would make sense as the pistol port is present on the left side. (Later turrets deleted the pistol port, had thickened cast-in cheek armour and a loader's hatch. This appears to be an earlier turret retro fitted with a single hatch TC cupola and vision blocks.)
Good luck with the project, and if you need any assistance with scratchbuilding a siren and guard for the glacis, let me know as I have built a few
