This is a terrific set and a terrific range (though you should fix the backpacks and perhaps the hats as well). With the same backpacks, they could also be used as British infantry in the Napoleonic campaigns in the Caribbean (Hispaniola, Guadeloupe and Martinique). Assuming this range sells well, Strelets should seriously consider expanding the range to cover the French Revolutionary/Napoleonic Wars in the Americas, including French troops for the Haitian Revolution, more British for the same period and even Haitians fighting for independence. It could also be a nice segue into the War of 1812, since it looks like Emhar/Imex are not going to be making any new figure sets in the foreseeable future, if ever.
And, if you ever feel more adventurous, you could always plunge into the Latin American Wars of Independence period.
