The first set of results seem to favour May 1981 - the CO (middle top) as Cdr Chris Wreford Brown who went on to command HMS Conqueror. The photos show Dreadnought entering Plymouth - (Guz) to navy people. Land marks being Fort Pickelcombe, Mount Edge , Drakes Island and coming alongside  9 wharf opposite the squadron building HMS Defiance.
