That's interesting. Be great to see those photos.
It certainly looks like the TLC tank in the rotting car photo - with the rail over the track:
It'd be a long shot if it was a Mk VIII tank from some other production that happened to be parked alongside.
There was no indication as to when this picture relates to, so I was hesitant to say that it shows the current condition of the Citroën. Sad to see it in that state, though, even if it was a replica made for the film.
