My buddy Dean R. painted up this set of British Legion infantry for me. I assembled the unit by combining our bodies at attention with heads in Tarleton hats. Both are available through the Recruit Your Own Regiment menu on the All the King's Men website: link
The uniforms are perhaps a little bit too dressy for Loyalists, but I wanted this unit to look striking, and Dean's painting paid off. The heads also have chin straps, a legacy from the heads being used for cavalry as well.
I went with a King's Color, because I like regiments with colors. The legion may not have carried one, but it does in my toy soldier world.
The two command figures are the same body, with different right arms. That alone does a pretty good job of making them look different.
This set is 54mm, metal, and comes in at $40 USD UNpainted from the ATKM site: link
