Thanks for that photo, I've not seen Ghillies like that.

Sadly the various Allen Brothers photos don't show the shoes clearly, just enough to tell they're some sort of Ghillies.

BTW I'm reading over the interesting correspondence between Sir Thomas Dick Lauder and Sir Walter Scott which Dunbar quotes at length, and another example of the Allen Brothers' opportunism jumped out at me:

(Sir Thomas writes)

"A curious corroboration of the accuracy of the manuscript, if corroboration had been wanting, occurred in the case of Lovat. Talking of his tartan he told the Messrs Hay that although the tartan he then wore was that which was always worn by the Clan Fraser as their Clan Tartan yet some old people of the name maintained that there should be a white sprainge through it. The Messrs Hay on consulting the manuscript found the tartan (therein) to be exactly as worn by Lovat with the addition of the white sprainge..."

How convenient! Another example of them quickly creating a tartan to fit with tidbits of information they came across.

Of course this incident must have preceded the Messrs Hay allowing Sir Thomas to make his copy; otherwise Fraser and MacLean both would have exposed the Allen's opportunism.
