18th century scottish regiments

[figheadair]

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.

All the Highland regiments at the time of the F&IW (generally referred to as the Seven Years' War in Britain) wore the 42nd (Black Watch or Government) tartan.

There are a number of portraits of the period showing the dress and arms of Highland soldiers (generally, officers) such as the Pinch of Snuff c.1760 by Delacour.
