The southern states DID proclaim their Scot ethnicity during the period. If you look at the Stonewall Jackson memorial currency note, it is covered with Scottish symbology.

I would not be SURPRISED if there WAS a CSA "Highlander" unit, but have NEVER seen any photographic or other solid evidence of there ACTUALLY being one.

Brett, are you seeking to portray a CSA Highlander unit (kilt and gear), or a highlander fighting in a "regular"/normal unit?
