Pipestud also often has vintage tins for sale.
BTW, if you don't know what you're looking for, some eBay listings can steer you wrong. It's not unusual for a seller to say a tobacco is "no longer available" and actually mean that "this year is no longer being sold at retail." They may be offering blends that are absolutely still in production but with a couple of years age on them.
Personally, I'm not sure I'd include GLPease blends in a discussion of vintage tins, since the most highly sought blends are only about a decade old now (his Syrian range, which includes Renaissance, Raven's Wing, Mephisto, and Bohemian Scandal). But if that means "vintage" to you, that's fine. Otherwise, I'd highlight the original Dunhill and Murray-produced Dunhill blends, Balkan Sobranie, Cope's Escudo, anything from Gallaher, A&C Petersen, Sullivan Powell, key-top Rattray's tins, Craven Mixture, older Three Nuns (round tin), Bengal Slices, tinned Condor, John Cotton blends, and anything from Elephant & Castle. Be aware, though, that some of these blends haven't been produced for 30-60 years, so they truly are "vintage."
