It looks a little too squishy to me to be ardennes but I thought of it...
My "E" clemence looks very similar to the first photo...but the 2nd photo looks more classically clemence for a bag that has been used and not babied. But I haven't seen clemence in that older green so I agree it could be ardennes. Post a close up showing the texture of the leather?
same thoughts Pepper: the color is not a clemence color (per what i know and recall) i wonder if the size of the bag (looks like a 40) makes it more pliable.
