Around the hull radio
The Tiger had a radio operator in its forward hull. Many items of equipment were stored around him. A Command Tiger had more, and different, items here.
Lower side wall
Ustar put some equipment in this area, but it's laid out in the standard way. These items were moved in Command Tigers to make room for a writing set (pad and pencil holder). Ustar's kit doesn't have the writing set.
The kit also lacks the gas mask container that should be here in all Tigers.
Front wall
The front upper wall of this area carried the hull MG position, which is provided in this kit. But a Command Tiger had a number of other items beside it; e.g. a "station clock" and a writing bench. They're not included in this kit.
Headlights
Ustar tell us to build the tank with its headlights removed, probably because they were removed during the Wittman photo shoot. But since this is an interior kit, we should still see the headlights. They should be in their dedicated holders inside the front of the tank. Ustar don't give us any of that.
