Assistance needed in the identification of this tartan.

[English Bloke]

Looks like The 79th (Cameron of Erracht) tartan, as worn by the Cameron Highlanders. One of the few military tartans not derived from the 42nd (Black Watch) tartan. I believe it finds it origins in the MacDonald sett.

Edit:

You can see it worn here by the Pipe Major and Drum Major of the Somme Battlefield Pipe Band in Villers Bretonneux, France, Anzac Day 2010.
