Welcome to tPF. First of all, it is against the rules to post links of your own eBay listings over here.
Secondly, not saying it is not authentic, but there aren't enough pictures to tell. Close up pictures of the Chanel trademark, the Made In, front and back of the twistlock closure and hologram sticker are needed.
Thirdly, the vintage styles didn't have any names, only the more current styles have.
