About this detail of the Tiger
Photographic coverage of the "Bergepanzer Tiger" is incomplete. It had a feature that seems to be a heavy-duty towing hitch, added to the rear hull wall. It is visible only in one photo.
In the photo, the feature sits between the Tiger's two exhaust heat shields. The feature seems to comprise two thick tabs with holes. We cannot see if there is a base plate.
No model kit of the vehicle contains this feature.
