About this detail of the Tiger
One of the two decal options in this kit, the one shown on the box art, is "S04". This Tiger was issued to Michael Wittman's unit while they were in Italy in late 1943. His crew were photographed with the tank early in 1944.
"S04" was not a standard Tiger but a "Command Tiger", an Sd.Kfz.268. Command Tigers were significantly different to standard Tigers on the inside. Rye Field's kit makes no allowance for this fact.
There was no turret MG in a Command Tiger. The standard radio set was installed in the turret instead, with its transformers, a special chair, and other accessories. The turret had as much radio equipment as the hull position in a standard Tiger.
This is the inside turret of the kit. An MG is included, and its accessories box is on the wall (both arrowed).
The real "S04" had a circuit board on that wall, bearing a large intercom box (drawn here) and other components. It had no MG because a large radio set was in that space.
There was no external MG opening in "S04"'s mantlet, but the kit has one.
The left-side wall of the kit gives you a circuit board with the two standard intercom boxes. The forward side of the wall is bare. This is correct for a standard Tiger of the time.
But "S04" had different intercom boxes (drawn here) and there was yet another intercom box by its forward wall.
Without going into illustrations, Command Tigers had non-standard features in their hulls also. An electrical generator was present, along with its accessories. The radio was of a different type. There were many additional electronics boxes and cables. Rye Field don't supply any of this.
The outside of a Command Tiger was only slightly different to a standard one, so this kit can potentially be converted to an external-only model of "S04". But the necessary parts are not provided in the kit.
