About this detail of the Tiger
The rear wall of Border's kit has many tiny squares. In a real Tiger, these are threaded blocks where equipment can be screwed on. Most of them are for the exhaust shields.
But there are four squares, marked in this photo, that don't get used by any parts in Border's "Kursk Tiger" kit.
These squares were for a storage tube to hold "star" antennas. Only "Command" Tigers had them. Standard Tigers were manufactured without these four squares.
Border's kit does not provide the other parts for a "Command" Tiger. You should remove these four squares for every decal option except for Tiger "S02".
