Some seem to stir the pot wherever they go. I personally would stick to the opinions of the very kind ladies and gents whom I have known here for numerous years who have demonstrated more of a desire to be helpful and fun. Just ignore the rest.
OP, I really hope you come to a positive resolution of this matter. I love Hermès and have become quite familiar with many of the product lines over the past 20 years - so much so that I am happy to educate newer SAs about older products and I really enjoy a good leather discussion/debate with our local craftsman-in-residence (there is one matter we have discussed where I am not totally convinced, but then again, I do not work with H leathers daily; however, I started collecting many years before he started training!).
I believe that Bababebi is correct based on the information she was given; beyond that, of course I cannot say. But based on my own personal longtime experience with Hermès, with other collectors and with my friends here, while I have no idea whether Hermès made a mistake, I believe that B did not. Both thoughts don’t have to be mutually exclusive.
Of course that doesn’t solve the problem but honestly, when you get to the point where you yourself (meaning me) have had to educate corporate employees about brand heritage, it’s not an unbelievable scenario.
I don’t believe H keeps a database of items produced with corresponding years and production info, do they?
