I was browsing on eBay and noticed that some of the BV bags have two rows of authentication codes on the tag. The top row is the usual number that we see on all, except vintage, authentic BV bags, 115653 V0013 2040, for example. The bottom row is another string of numbers. Does anyone know that that means? Is it normal for authentic BV to have two rows of codes on the same tag? I have seen some LE items that have 2 codes together, but on a regular classic style yet. Any information will be appreciated. I'm still trying to learn more about BV. The superb craftmanship and the quality of leather make me deeply addicted to it.
