In a Command Tiger, a generator was housed in the rear right-hand corner of the fighting compartment. One of the large ammunition bins was omitted from there, so that the generator and its associated equipment could use the space.
Here is Ustar's CAD image of this kit. Standard Tiger parts are coloured grey here, while the generator and other Command items are coloured red.
But Ustar have made a mistake. They removed the large ammunition bin from the sponson, but they kept a small ammunition bin (arrowed) in the floor beside it.
Command Tigers had no ammunition bin there. Instead there was a general purpose equipment bin ("Zusatzbehälter") [1] . We have no photos of that bin, but this German plan diagram shows us that it had the same outline as the ammunition bin. Another German diagram reveals that the top of this bin was level with the floor. [1]
We can speculate that this storage bin was made to much the same pattern as the ammunition bins. Therefore it's very likely that the bin had the same kind of lid as the ammunition bin that it replaced.
You can therefore improve the accuracy of Ustar's kit by cutting the bottom away from this particular ammunition bin and placing it lower down in the hull, so that its lid is level with the floor. Remove the two clasps, because they would have been inaccessible.
