I have a feeling we've discussed this before, but I can't remember where. However, Witold Lawrynowicz says, "A camouflaged St Chamond of the 2nd battery, Groupement lll. It has a non-standard observation turret in the rear, most probably made in the field workshop from a trench observation turret. The tank is named "Chantecoq" and bears a beautiful painting of a crowing cock. The photograph was taken in June 1917."
