For more on marking an answer as the "Best Answer", please visit our FAQ.If, as people seem to be suggesting here, only A/B/C/D now exist and that they refer to yearly quarters, what could 'Z' have represented in the 1950s? There has got to be more to this than quarters, I'm afraid.
I don't know when the A/B/C/D system came into use but it certainly didn't apply 50 years ago. That's why I'd still love to find out what these letters actually did stand for, given that - whatever they mean now - they clearly had nothing whatever to do with yearly quarters back then.
(Of course, the reason you don't see such things in the course of your daily work is the fact that my age-group has now retired and is reaping the benefit of all these NI contributions!)
