Kinloch Anderson attributes this pattern as 'Based on a piece of kilt believed to have been worn at Sheriffmuir. (13th November 1715) Olive green or Grey/green. 'Old and Rare Scottish Tartan' was written by D.W.Stewart and published in 1893.' When woven in muted or old colours weavers inexplicably insert a black guard on the white. As this swatch is in Modern colours, there is no black guards on the white stripe.
