My father's archive includes correspondence with Buckingham Palace from not long after her Coronation exploring the possibility of her visiting the Corps of which she was Colonel in Chief. The exchange of letters concluded in 1957 with arrangements for a visit to Deepcut.
The visit took place on 11 April 1958 and the Queen was hosted by Major General Sir Lancelot Cutforth as Director of Ordnance Services and my father, Major General Sir Leslie Williams, as Colonel Commandant. This is one of the photographs taken of the visit.
There is a film of the visit which I am sure is held at the RLC Museum. There are further photographs in my father's archive which is also held at the museum.
