Not sure about the switch from KGVI to QE2 but around mid 60s we all had to change buttons on No1s and Great Coats to high dome. The problem was No1 button holes had been sized for the earlier slimmer button. There was no question of not changing it was a direct order.
I remember many aircrew with WW2 medals. They all sported QE2 crowns.
