Just reading the item in Landships II, about the Renault TSF.
There are four known survivors, none complete.
In addition to Saumur's example, there's one at Fort du Zeiterholz, Entrange
Another at Fort du Hackenberg, Veckring
And a fourth one has surfaced in Poland.
Oh, plus parts of one making up this.
