Hmm, I sewed a lot in the 80s and this feels different to me than what I recall... I'm not sure how to describe it, exactly, but I would say the fabric is finer and somehow feels a bit -- drier? Does that make any sense? And the selvedge looks a bit different, more narrow, and finer, and less perfectly finished than fabrics I recall from the 80s. But I am aware there's always the temptation to date things earlier and all this info is helpful, thanks!
