If I recall correctly, the Scots Guards pipers adopted the feather bonnet in 1928.

About that Black Watch piper, remember that that photo was taken on active duty in India and he is not wearing Full Dress. Look at his jacket: the Service Dress jacket of the time, not the Full Dress doublet.
Black Watch pipers, as far as I know, have always worn feather bonnets in Full Dress ever since that headgear evolved.
