Since this thread on the subject of regimental tartans has come again, I thought I'd take the oportunity to ask a rather dumb question. The majority of the regimental tartans seem to be "clan" tartans instead of a design specifically for that particular regiment. Is there a reason for that? Does that fact tend to "generisize" those tartans? Hunting Stewart has been worn as an open tartan for some time... what about Davidson or Mackenzie for example? Just curious...
