Avon & Somerset Constabulary: Headgear - Peaked Caps ...
Cap bands Police in Scotland were the first to adopt a form of chequered band (also known as Sillitoe Tartan) on their peaked caps. Bands on peaked caps are used to distinguish different enforcement roles. The current Police chequered cap band was first introduced for the UK in the early 1970's. Police only use black or very dark blue versions.
