Hello, I hope this is the correct forum. I just purchased a vintage hermes bag similar to the noumea style and it has 3 stamps. One is a O in a circle, then a Z on its own, then a horseshoe. From reading different threads on here, I am wondering if the first stamp is the year, the second stamp is the place where it was made and the horseshoe means that it was a special order (like a different color combination or thread color). Is that correct?
