Durham Constabulary was one of the first county police forces to be set up, established in 1839. The force absorbed Durham City Police (formed in 1836) in 1921, Hartlepool Borough Police (formed in 1851) in 1947, Sunderland Borough Police (formed in 1837) in 1967, and Gateshead Borough Police (formed in 1836) and South Shields Borough Police (formed in 1839) in 1968, when it also lost some of its area to Teesside Constabulary. Northumberland County Constabulary absorbed Berwick-upon-Tweed Borough Police in 1921 and Northumberland Constabulary was created with the amalgamation of Northumberland County Constabulary with Newcastle upon Tyne Borough Police and Tynemouth Borough Police in 1969, more than doubling its strength. In 1974 it merged with part of Durham Constabulary to form Northumbria Police. Both plates are in good condition. The price includes UK delivery. BA 888.
