Considering 3 factories made the M4A1 hull and that each made various changes and tweaks to the casting on each production run , I think the bow gun mount looks pretty good . Personally , I would add putty or green stuff to the turret and hull any way and stipple it to get the correct texture of the real cast hull vehicle I'm using as inspiration for my model . In fact I do that for all my tank kits that have cast parts ( lots of rough cast bits on T-34s ) . Unless Rubicon decide to depict a specific factory's product , giving month and day of manufacture , I'm willing to give them some slack on fidelity of details .
