Appears to be three turret bases - two on one sprue, one on another.
Also, those two cones...

Which one is the first to have the turret skirts?

F?

I would be thrilled with a complete engine compartment, forget the full interior!

In response to Frank:

Yeah, none of that in Africa as the threat they were meant to encounter wasn't present. As far as schurzen in the ETO I believe procedure was to put plates on vehicles heading to Russia to counter their AT rockets, which was not an issue in Western Europe. Obviously I can't say the moving of units around the map caused some schurzen tanks to end up on the West. But it is possible, I would imagine. I can neither confirm nor deny the existence of schurzen on anything but Russia-bound tanks.

Jagdpanzer IV?

You seem to get your wish with them showing a CAD of the Maybach engine, though not clear if it's included or separate add on.

Cor, not this old chestnut again.

Schuerzen were intended to counter the Soviet anti-tank rifles, which obviously were not found in N Africa. They were nothing to do with anti-tank rockets, as the only type the Red Army used was captured Panzerfauste.

Obviously they did appear in the west too but that was probably more about it being easier to standardise than to design vehicles for one specific front. And obviously units did transfer en bloc between fronts anyway.
