Yes, the M4 kit requires one in order to build it as a large hatch high bustle 105mm tank. All of those tanks were final production for M4 line, the all had late FDA cover with sharp nose.
The M4 hybrid requires it too, once the early small hatch hybrids ceased production all subsequent large hatch M4 hybrids had the late sharp nose FDA too. It was also a final production model.
I don’t care that we didn’t get them in the kits, I just want to be able to buy resin final FDA as replacements for the kits that are missing them.
The final FDA was not restricted to 76mm Sherman variants although ALL 76mm had sharp nose covers. Many 75mm variants also had them.
