Note on the 21 century Pz IVs...just did a lot of reading to make adjustments and convert mine to different models. I now have a D, E and H model with another due in to become a Befehlswagen with tube antenna and dummy gun. The TC hatch cover is wrong. The one piece, circular hatch came out with the H model. All other Pz IVs had a split hatch for the TC, to include the F1 and F2 models. . Simple job to cut the hatch down the middle, make a hinge and cement both halves in place.
