Tiger 121 was apparently demolished at the end of the Tunisian campaign. The separation of the turret roof is unlikely when a tank is knocked out. This is a still image from a newsreel that shows British forces taking the Tiger's turret away from the wreck site, on the back of a recovery truck.
An air intake grating lies inside the turret shell here. The turret's inside walls are blackened by fire and the internal storage boxes are missing from their mounts, another sign of an explosion. An electric cable on an insulating backboard runs around the inside turret wall near the roof; this was the earliest layout of the Tiger's turret wiring.
