Fire insurance marks are metal plaques marked with the emblem of the insurance company which were affixed to the front of insured buildings as a guide to the insurance company's fire brigade. These identification marks were used in the eighteenth and nineteenth century in the days before municipal fire services were formed. The UK marks are called 'Fire insurance plaques'. The first to use the mark was the Sun Fire Office which was established in 1710. Some period specimens remain on historical buildings in the older areas of Britain's and America's cities and larger towns. Cast metal plaques were made of iron, lead, or sometimes brass. Embossed sheet metal signs were also made, as well as flat enamel signs – the latter mostly in Continental Europe in the later 19th century. Period specimens may have high value among antiques collectors, leading to illicit creation of fakes. Also, nostalgic reproductions have been made since the early 20th century for decorative purposes. By location British For most of the 18th century, each insurance company maintained its own fire brigade, which extinguished fires in those buildings insured by the company and, in exchange for a fee to be paid later, in buildings insured by other companies. By 1825, fire marks served more as advertisements than as useful identifying marks; some insurance companies no longer issued fire marks, and those that did sometimes left them up after a policy had expired. Successive combinations of fire brigades led to virtually the entire city of London being put under the protection of the London Fire Engine Establishment, which fought not only the fires of policy holders but those of nonsubscribers, the reason being that fires in uninsured buildings could rapidly spread to insured buildings. The Museum of English Rural Life has a collection of 100 fire insurance marks from around England. An urban myth around fire marks claimed that if a building was not insured with the fire mark of a particular fire brigade or a company they had a reciprocal agreement with, they would let the building burn. However, following a review of contemporary evidence, it has been argued that this was not the case in the vast majority of fire incidents, and fire brigades would attempt to extiguish any fire regardless of insurance status due to threats to nearby structures, financial incentives and the publicity it gained.
