Cheers for that link.
After further reading of the thread on that forum it appears that there is a Tiger II still buried under a road in France, its turret is above ground and appears in a couple of photos. From what I can see it is too expensive to recover the Tiger II, and no one is willing to pay for the job.
There is also mention of a Panzer III:-
"Now if you really want a German tank it must still remain a PzIII in Lyon, it is at the bottom of the Saône under a bridge I think ... And no more than 4m deep. The only worry is the authorization of the City: Never given despite several projects very well tied."
And mention of a Tiger I:-
""Tiger I in France, perhaps one along the Seine north Paris, but in very bad condition it seems."
And mention of another Tiger II:-
"A Tiger 2 was found in a monastery in Normandy in the early 80s, but negotiations with the responsible would hooded, the latter requiring an astronomical price."
Does anyone have any more info on these?
