What would really be nice is to have the Panzerkampfwagen VI King Tiger with the two different versions represented. The initial with the Porsche style turret and the Henschel style turret. 
They were both Krupp style turrets. But the initial production run of 50 was originally intended to be mounted on the Porsche chassis. But Porsche lost the competition to Henschel and the turret designed for the Henschel chassis was not yet ready for production thus they used the "Porsche" turret on the initial models. This turret had some drawbacks, it needed more raw materials and needed mor manhours to produce because of the shaped surfaces. And it created a shot trap, a shot deflected from the rounded gun mantlet may penetrate the chassis top armor.
AFAIR the initial calling the Tiger Ausf. H or Tiger (H) was a manufacturer code, the Porsche Tiger was called Tiger (P) thus the Tiger (H) was Tiger (Henschel). Does still not explain why they later used Panzerkampfwagen VI Tiger Ausf. E (instead of Ausf. A) and Panzerkampfwagen VI Tiger II Ausf. B .
