Footnote: The honour of the Knight Bachelor dates to King Henry III (1207-1272), but it was not until April 21, 1926 that a distinctive insignia was introduced at the request of the Imperial Society of Knights Bachelor... and until 1998, recipients had to purchase one. The Knight Bachelor's Neck Badge (1973 to date) is awarded to those on whom Knighthood is conferred, unless as a member of one of the Orders, when the appropriate badge would be worn. It is the only insignia presented at Investiture, the other badges are private purchase items.
