18th century scottish regiments

[timemeddler]

Trying to find information on Scottish regiments around the time of the French and Indian war, and the American Revolution. I'm mostly trying to find out how they would have been outfitted at the time, since they would have been part of Britain. Would they have used the same brown bess as the British Regulars or did they have their own? Tartans they would have worn? The internet is pretty limited on what they had as soldiers.
