They went into the 80’s with Vanson and Bates m/c gear. Brooks too.
I actually have the YKK and Talon version on this jacket:

Yep, they go well into 80's for some makers. Apparel Annex used them all the way until they went under and like you said, they were pretty much trademark of Brooks cafe racers. I think it is safe to say that most jackets with them are from the seventies. Rarely earlier.
