About this detail of the Tiger
This kit contains enough optional parts to build almost any Late Tiger. It has 4 decal options.
We don't have enough photographs of those 4 real Tigers to specify all the parts that they need, but we do have some photos, and we know their approximate build dates, so this is what we can say about them. (Refer also to my other comments about the kit.)
The following parts are not needed: Z6 (the cupola with drainage slots); P14-P12-P25 (the small muzzle brake); P2 (the mantlet with one eye hole).
Tiger "312" needs; Z12 (the loader's hatch with short hinges); P20 (the side hatch's short hinge).
Tiger "221" needs; P20 (the side hatch's short hinge). We don't know if the loader's hatch should be Z12 or Z13.
Tiger "1" needs; Z13 (the loader's hatch with long hinges); P20 (the side hatch's short hinge).
Tiger "007" is very different to the other decal options, and the kit instructions are clear about this. We don't know which turret roof is correct for "007" but it is almost certainly Z1, as the instructions say. The loader's hatch should be Z13.
