Sorry I don't know about the WSG company.
But yes it's an old 93rd Foot / Argyll & Sutherland Highlanders sporran.
That sporran was worn by Other Ranks of the 93rd Foot (Sutherland Highlanders) from c1830 to 1881.
In 1881 the 93rd became the 2nd Battalion The Argyll & Sutherland Highlanders (the 1st Battalion was the old 91st Foot Princess Louise's Argyllshire Highlanders).
Here's that sporran being worn
Here you can see three different sporrans worn by members of the Argyll & Sutherland Highlanders
-grey sporran, at left, worn by pipers
-badger mask sporran worn by the sergeant and officer
-OR's sporran worn by the other ranks.
