I was thinking the same thing and I was wondering why I did not see more scratches on this bag.I am absolutely no expert, so take this with a grain of salt, but if this is barenia from 2013 I would have thought it would have a lot more patina. This looks very light and even coloured to me.
Or Chamonix maybe? Sorry I really am no expert! A picture of a stamp may help (barenia should be a blind stamp, no colour I think) but I’m sure someone who knows more will come along soon.It is a White Bus. I am wondering if it might be Vache Hunter or Natural??
It looks like it could be Prune to me. But I’ve no idea which year Prune was available or if it came in this model. Hopefully an expert will come along soon!
