I took a few photos while assembling the Nashorn model by Revell. Here the hull is seen from the left front (top photo) and right rear (bottom photo). The gap in the front in the upper photo is due to the upper deck not yet having been glued in place. Painting is done wherever gluing is completed or there's nothing to glue in place (such as the floor in the lower photo). Interestingly, the tracks in this model are made of rubber. Otherwise many of Revell's tracked vehicles have tracks made of plastic to be glued in place. This allows painting the tracks. I have 2 more construction images I'll post. Enjoy!
