I have been following this thread from the start and I have to say we can debate until the cows come home on who has more expertise (H craftsmen or the authenticator) but at the end of the day, only H's opinion matters. So why not everyone just take a chill pill and wait for OP's further updates 
To OP, if it offers you any consolation, I casually showed the pictures to a close friend who worked in my home store for several years and she agreed that the bag in the pictures is no doubt authentic. In addition, if the store that accepted your bag had any doubts, they should have not accepted it on the spot, that's the practice my store adopts (though it's not explicitly stated/mentioned). Did your store hinted in any way that they have doubts?
Anyway, I really do hope that this matter solves in your favor. Good luck.
