Possibly an officer cadet at the OCS Eaton Hall, Eccleston, Cheshire with the uniform made in Chester.
In the 1950s, candidates for National Service commissions, which were unlikely to last more than two years, received a cut-down version of officer training, lasting for sixteen weeks, either at the Mons Officer Cadet Training Unit at Aldershot or the Eaton Hall OCTU near Chester.
