A post 1953 Constable's or Sergeant's uniform helmet of the former Glamorgan Constabulary. Constructed of cork with outer covering of wool. Glamorgan wore this style of helmet from the latter part of the reign of Queen Victoria until a change of uniform and helmet design in the early 1960's. The Glamorgan Constabulary ceased to exist after 1969, when the South Wales Constabulary was formed by amalgamating Glamorgan with the police forces of Cardiff City, Merthyr Tydfil and Swansea Borough.
