I had a quick look "here" (no hits at all) and at http://www.landships.freeservers.com/sitesearch.htm (numerous hits) and http://www.chars-francais.net/new/index.php?option=com_content&task=view&id=48&Itemid=37 (many pictures) - and this appears to be a picture of the FCM 2C that is not in those other places - http://www.schizodoxe.com/docs/2009/05/1lf7cier.jpg. No idea what its provenance might be - the above and one other secondary source are all I have found for it. Anyway, it struck me it might be a useful quick-and-dirty 'scaling shot' of that char. Not that I've noticed any quick-and-dirty modellers around here.
