As I recall, the RAF went over to staybrite buttons around 1968, certainly I wore brass buttons for my first few years of service from 1964.
We were still polishing brass buttons and picking the duraglit cack out of the crowns in 1969 at RAFC. Then came 'low dome' staybrite buttons, but they were soon replaced by the current 'high dome' version.
