Thank you for responding!
The bag in question (my bag) is actually the Garance. I was shocked to find two date codes, one on the underside of the leather trim of the zipper and the other inside the removable pochette. But because I bought my bag from a consignment site, I really was quite anxious that I had purchased a great quality FAKE. One of the other members on this site had also told me that it was normal to have different date codes for some bags with removable pieces... and then I stumbled upon your post during my research.
Again, I really appreciate your response!
Have a great week!
No worries Congratulation on your Garance. It is a very beautiful bag Enjoy in good health
