The Calculus Affair
In "King Ottokar's Sceptre", the Bordurian flag is black with a red circle and two black triangles, reminiscent of the stark, eye-catching symbols used by several Fascist movements. In "The Calculus Affair", it is red, with the emblem of Kurvi-Tasch's mustache inside a white circle, resembling it closer to the Nazi flag, and this was also worn as military armbands by the Bordurian military personnel. In "King Ottokar's Sceptre", the Bordurian army uses the Gewehr 98, vz. 24 and Karabiner 98k bolt action rifles. In "The Calculus Affair", Bordurian soldiers and agents were armed with Italian Beretta Model 38 Submachine Guns. Due to the nature of its government and its military's weaponry, Borduria was most likely an affiliate of the Axis during World War II, although there is no explicit mention of that in the books.
