I've checked the lock/key threads and can't find an answer so hoping someone out there can explain it to me. What do lock numbers correspond with? Bag model? Place of manufacture? Years of manufacture of a model? I've noticed some numbers seem to reappear in mid/late 90s epi bags but I don't own enough to generalise. I know most people don't care about the locks, don't always keep them on the bags, and one can put any LV numbered lock on any bag and nobody would really care but I figure LV probably has a system, nothing is by chance. What do you think? Any insights?
