Army pipers uniform, RRS (part 2)

[blackwatch70]

One is the revival of the old 1970s MOD short (14") horsehair sporrans, with the clumsy-looking chrome cantles, for the drummers of 2, 3, and 4 SCOTS. Why? The generic RRS sporrans worn by the drummers of 7SCOTS look much better.

I think this is not a revival but as well as pipers, drummers just inherited those sporrans from legacy regiments P&Ds (RHF, Black Watch and the Highlanders )...
