The set has individual dials that have to be cut from the fret and added to the plastic part of the model
There are two options for the central dial, with white or black background.
There are also two placards with vehicle information. again the set has two options for the one inside the cabin

Conclusion
This is an excellent set for the Krupp Protze kit, specially for the open top version where the improvement will be more noticeable. The level of detail is beyond what can be seen with a naked eye, and photos will reveal its finesse on a finished model
