The Tiger had a manual starter motor, with a typical handle. This handle broke into two parts for storage. The straight shaft was stored in clips at the bottom of the tank's rear wall, while the L-shaped portion was put somewhere inside the tank.
This kit provides a fully assembled starter handle. This is not something you would normally see on a Tiger.
The kit's preview CAD images suggest that the designers intend to put the complete starter handle on the rear wall (for some versions of Tiger at least). Obviously, that would be bad practice in reality. As soon as the tank goes through some foliage, you will lose that handle. Why would the kit designers think this a good idea?
As far as I can tell, the British prepared drawings of a captured Tiger during the war, and because they did not know the vehicle very well, they drew the handle in this configuration. And then, as I have seen in several books, artists used those British drawings as source material for more illustrations, repeating the mistake.
Nothing should be stored here except the handle's straight shaft, which is also provided on the "test shot" sprues and is expected to be in the final kit release.
