Bought this on eBay recently. The description has is as
Weathered Glen Craigloch Tartan woven in Scotland by Peter MacArthur of Hamilton (Now sadly closed )


I've been unable to find it as a registered tartan on the Tartan Ferret or Scotweb, so I assume it is just a fashion tartan.

But.... with so many more knowledgeable people on this forum, though I would post it and see if anyone has more information.

Thanks,

Brian
