About this detail of the Tiger
The Tiger or Tigers addressed by this kit were coated with "Zimmerit" when in service. This should be added by the modeller for accuracy. Note that a few different patterns of Zimmerit were used on Tigers built at different times. The pattern is different again if the coating was added to upgrade a serving Tiger.
If the tank has been in battle, damage to its Zimmerit coating is likely.
The Zimmerit coating tended to weather off over a period of a few years. If you are referring to photographs of wrecked Tigers taken after the war, they will not give you a clear picture of how the vehicle appeared in service.
