Until 1926, Knights Bachelor had no specific insignia which they could wear, but in that year,
King George V issued a warrant authorising the wearing of a breast badge on all appropriate occasions by Knights Bachelor. This badge is worn on the left side of the coat or outer garment. Measuring in length and in width, it is described in
heraldic terms as follows: Upon an oval medallion of
vermilion, enclosed by a scroll a cross-hilted sword belted and sheathed,
pommel upwards, between two spurs,
rowels upwards, the whole set about with the sword belt, all gilt. In 1973,
Queen Elizabeth II issued a further warrant authorising the wearing on appropriate occasions of a
neck badge (of smaller size) and a miniature medal. In 1988, a new certificate of authentication, a Knight Bachelor's only personal documentation, was designed by the
College of Arms. ==Imperial society==
