I hope that it is appropriate for me to ask this question. I'm a long-time Hermes scarf collector that finally moved into their bags as well. I had heard that authentic Hermes locks, on their underside, have a "dimple" on each side of the actual place where you insert the key. Last night I looked at the underside of my locks. Surprisingly, on 2 of them, both which are marked "120" and in gold, there are no such dimples, which I did find on others. One of these 2 "missing dimples" locks is from a bag that I bought at the Tyson's boutique last spring; the other is from a bag I bought from a trusted reseller. For both, the keys (all marked 120) that came with one bag will open the lock that came with the other. Has anyone else experienced this? Is it possible that not all authentic locks actually have both dimples? Or should I instead be worried about the authenticity of these 2 bags, even the one that I bought at the boutique? TIA.
