context_page_description: London District Signals was a headquarters signal unit of the Royal Engineers and later Royal Corps of Signals in Britain's Territorial Army from 1908. It served with a corps headquarters at Gallipoli and on the Western Front during World War I, and later became an air defence signal unit during World War II. Its successor unit continues in the Army Reserve today.
context_section_description: When the renamed Territorial Army (TA) was reconstituted in 1920, London District Signals was reformed as 1st London Corps Signals (Army Troops) in the Royal Corps of Signals. It was retitled as Anti-Aircraft Signals in 1922, and then Air Defence Signals in 1925 when it formed 26th (London) and 27th (London) Anti-Aircraft Brigade Signals Companies. When 1st Anti-Aircraft Division was formed at RAF Uxbridge in 1935 (with 26 and 27 AA Bdes under command), the unit provided the signals component. It was based at 46 Regency Street, the former Drill Hall of the London Electrical Engineers. The divisional signals unit was duplicated for 6th Anti-Aircraft Division in 1939 when the TA doubled in size after the Munich Crisis. 6th AA Division took responsibility for the air defence of the Thames estuary, Essex and North Kent, with its HQ at RAF Uxbridge.  Just before mobilisation, the regiment organised as:
  Regimental Headquarters at Regency Street, London commanded by Lieutenant Colonel A. Hemsley, MBE, TD
  No.1, 2, and 3 Signal Companies at Regency Street, London
  Cadet Affiliation — 'D' Company, 1st West London Cadet Corps
