They are all King & Country. Here's a quote from the book about the figure of the Sergeant Major with the Swagger stick:
"By 1987/1988, King & Country added additional red and khaki Coated Seaforths in many action poses, along with “Mixed Battle” sets (rearranging various highlanders into new sets), . . . [including] HBCS (a color sergeant marching with either a rifle or a swagger stick), . . . retailing for $19."
Here's a quote about the Napoleonic Highlander:
"By summer, 1994 King & Country added a set of six marching 79th Cameron Highlanders from the battle of Waterloo (NAP.WH) . . . The Cameron’s march in the identical pose of the above described British Grenadiers, wearing black feathered highland bonnets with white plumes, identical red tunics and packs, but green with red and white Cameron tartan plaid kilts, white sporans with black tassels, white with red diamond knee socks under gray gaiters and black shoes. . . . The six Camerons originally retailed for $76"
Here's a quote about the Napoleonic Mamaluke:
"By Spring, 1995, King & Country had released . . . a walking member of Napoleon’s Egyptian Mameluke bodyguard (NAP.EM) . . . The Egyptian Mamelukes, sold in sets of six, stride forward with their left feet and right arms forward, and their left hands resting on the hilt of their scimitars. They wear maroon vests and baggy pants, maroon and white turbans, white, black and gold shirts and gold sashes around their waists. The set of six originally retailed for $76."
Here's a quote about the Dismounted French Cuirassier:
"[In November, 1993 K&C released] two dismounted French Cuirassiers standing, smoking pipes (NAP.FC) . . . The dismounted French Cuirassiers stand with their right fists on their right hips, holding pipes in their left hands, with bent left arms, in front of their breast plates. They wear a silver Roman Style horsetail crested helmet with red plume and black crest, silver cuirass (breast and back plate), red epaulettes, blue tunic, white gauntlets, yellowish tan pants, and over the knee black boots. This set originally retailed for $28."
