This is an Imrie Risley 54mm metal kit and depicts an officer of the Blackwatch from around 1776.  The Highlanders were a major part of the British forces sent to the colonies.  They were often the shock troops of their day.
He wears the light blue bonnet with single ostrich feather, crimson coat, with a pistol slung from his left shoulder. His tartan cloak is also slung around his shoulders. He leans into his claymore sword in front and of course the figure is rounded out with argyle socks!
