Little model toy soldiers wearing the Coldstream Guard uniform (I found many variations of the uniform over the years so this is a bit of a mish mash). Her Majesty's Coldstream Regiment of Foot Guards is the oldest regiment in the regular army originating in Coldstream, Scotland in 1650. They've fought in 117 battles, and are famous for Royal ceremonial duties.
