There is a very good photo-journal of the restoration of Tiger 131 and in the lower photograph on page 36 there is an unexplained ‘repair’ to the deck armour below the damage to the gun-mantle:

While not exactly conclusive it would seem to be an extraordinary coincidence that this tank had suffered two pieces of unrelated battle-damage at almost exactly the same point on its armour (and one of which caused the crew to abandon the tank). According to the photo-journal the main-gun counter-balance was also damaged (my thinking is that it was by the same shot that hit the gun-mantle). I don’t think that many crews would have stuck around after that point.

I think the King Tiger engine threw a rod through the side of its block by-the-way! 😉
