Define "olden days". :P
What you have to remember is that, before the internet, most folks generally bought from a local store. Many smokers bought from their local drug or grocery store. That meant that what they had available to them were American blends, along with some of the Dutch or Danish blends. (Amphora, Troost, Sail, MacBaren, Flying Dutchman.)
The English blends, which had the latakia, tended to be available only in pipe shops.Some pipe shops sold by mail order, but you had to know about them - and some pipe shops only sold their own blends.
There were American blends with latakia - Revelation, Country Doctor, Barking Dog, Spillman's, Blue Boar, and probably others I don't know about - but not that many.
Lots of the old-timers, I would, had one or two blends that they smoked, just like someone smoked 1 brand of cigarette - and they were probably American blends, because they were ubiquitous and inexpensive.
