Los Angeles was a piping paradise when I started smoking in 1971. Besides all of the Tinderboxes, including the Original Tinderbox, going strong since 1928 in Santa Monica, there were a number of independent tobacconists who sold a wide variety of blends, many made in-house, and who would make up a custom blend just for you. You could buy tobaccos and pipes at Sears, Robinson's, The May Co, and pretty much any department store, as well as drug stores, grocery stores, convenience stores, etc.
And while there was no Internet, there was this thing called "mail order" that was a big thing, with companies like Wally Frank supplying pipes and tobaccos to anyplace that had mail service. So people did have wide access to goods even in very rural areas ir they wanted to use it.
We didn't have the thousands upon thousands of tinned blends that we have today. With all of the in-house blenders, we may have had more, but as far as imported tins the selection was less. But we certainly didn't feel like there weren't choices. We just didn't have 100 different labels that tasted exactly the same.
Curiously, Dunhill blends were actually made by Dunhill, rather than being just a now deceased name attached to a foreign comglomerate. McConnell blends were actually made by McConnell. Rattray's were actually made by Rattray's and McConnell. By and large British tobacco blends were actually made in Britain by a number of individual and idiosyncratic manufacturers. They weren't just a bunch of labels owned by the same company.
Then as now, people did or didn't collect pipes, and did or didn't collect a variety of tobaccos. Most of the people I knew back then had maybe a half dozen blends at most that they smoked. The majority had one blend that they smoked regularly, only occasionally supplementing it with something "special". If anyone was smoking a few dozen blends on a regular basis, that would have been quite the anomaly.
Nobody talked about cellaring. Why would anyone do that stupid? Tobaccos were aged before being made available for purchase. I'd just pop in at one of the tobacconists I frequented and pick up an ounce or two.
Even back then I liked a variety of blends and would rotate between 4 or 5 on a regular basis, then swap one out for something different when I was getting bored of it. I might mix in some Carter Hall or Edgeworth from time to time, I became fixated on Captain Black for awhile and that became my only smoke for a time. Balkan Sobranie and 759 were regulars, Three Nuns when it was around, as well as a number of in-house blends that no longer exist in memory.
