Thanks for that and very interesting under that link to Pattern 1914 equipment, where an image shows the S belt buckle being worn, says it was make primarily for "Pipers and Range Takers". Range Takers I know were trained units attached to the Royal Artillery and Machine Gun Corps, and I suppose it makes some form of Military sense that men with that capability of assessing ranges would train as snipers if they were good shots. Anyone with Military knowledge over that period that might shed some light on that, esp[ecially with the Scottish Regimental connection? There was of course an over kilt used in WW1 made of cloth/canvas to keep the mud off so that may explain the plain kilts in the photograph!!!
