If I said it was slightly lighter grey in real life would that make a difference? Or is that still completely wrong?
Basically, from mid-1943, the "standard" factory finish was "Dunkelgelb", i.e. a dark ochre yellow. To this, camouflage would be applied by the receiving units. I don't want to be picky, and I absolutely LOVE Panzers in Panzergrau (i.e. dark grey); and I will probably convert one of Tamiya's IV J tanks to an F1. or G, depending on how powergamey I feel, but the combination of this model of long gun barrel, commander's cupola and the turret skirts (I assume you left off the side skirts) is fairly typical for an H (or even J) and those, to my knowledge, didn't come in dark grey anymore.
That said, I'd be happy to be corrected with evidence if I'm wrong.
