This kit includes the gunner's pedal assembly on the turret floor. The rotation control pedals and the MG pedal with its linkage are both represented quite well. But all four side walls of the frame (arrowed) are solid.
This is a real unit in an "Early" Tiger. It has large holes in two side walls, which are visible when the tank's turret is taken out of the hull.
Another error is that Trumpeter's part seems to be based on the "Early" version of the unit, but their model is supposed to be a "Late" Tiger. It should have the lever and gearing that can be seen on the right of this photo.
