About this detail of the Tiger
All of the Tigers represented by this kit had the Zimmerit paste coating. Trumpeter have created their own solution to the problem of modelling this material. The kit contains sheets of thin textured plastic, pre-cut into panels that fit the model.
However, Trumpeter have given their Zimmerit sheet a near-perfect uniform pattern of ridges everywhere. There is no variation at all, and no adaptation to the edges of the panels.
Real Tigers had non-uniform Zimmerit. It usually had a different style on hull versus turret, which were manufactured in different factories. Also, the ridges were carefully shaped around the edges of the plate and the objects on the surfaces of the plate.
