WO 3801803-1991Office of the Commander-in-Chief and War Office: Adjutant General's Office: Designation, Establishments and Stations of Regiments, Returns and Papers (Regimental Records Series I-IV)
Records of the establishment, effective strength and disposition of individual regiments, with notes of changes to regimental designations colours and uniforms. These are thought to have been maintained by the Adjutant General's Office but latterly were kept in the Ministry of Defence library, where they were probably used to answer historical queries about British regiments.
