i have seen this guide, is this true? http://www.ebay.com/gds/GUIDE-CHANEL-SERIAL-NUMBERS-BY-YEAR-MANUFACTURED-/10000000177190204/g.htmlThe Serial # won't tell you that. The tag would tell you that. If it says 00V it is classic permanent collection. If it starts with say 14A (or similar) it's seasonal. Also if it's black it could be permanent or seasonal, as I believe there were different leathers in recent seasons. (someone with more knowledge on the Cerf can jump in...) If it's anything other than Black than it's definitely seasonal.
ETA: Just saw your picture, since it's Black I'd really need to see the tag. As I said hopefully someone with more knowledge of the Cerf Tote can comment.
Thank you for all your help I did get a strap but don't think this style of bag works with the strap, I am a bit disappointed with the weight and concerned he squashy this bag might get in several years, I was torn between this one and the timeless tote , I think I might send it back till I am totally sure xx
