The bulk of the correspondence is that formerly housed in the office Welensky maintained in Old Lonrho Building, Salisbury (Harare), under the superintendence of his daughter, Joan Bridge. This was shipped to England when Welensky retired there in 1981. A small number of the files, from c. 1964 to 1966, had already been despatched to Oxford with the pre-1963 archives. With them came Welensky's correspondence with Miss V.J. Betts of Birmingham, a lady unknown to him whom he was never to meet. That a stranger should continue writing with such frequency, and that she received considered replies with regularity, serve to indicate one of the strengths of Welensky's character.

See also the files relating to visits (MSS. Welensky Papers 708/3-711/7) in which arrangements to see various of Welensky's correspondents, particularly those based in London, are contained, and the Arundel by-election files MSS. Welensky Papers 720/1-722/2. During the Arundel by-election campaign and the immediately preceding period, various letters are no longer to be found within the surviving Welensky papers: the Salisbury papers at Hatfield contain certain such letters from Welensky to Lord Salisbury; and the papers of Sarah Gertrude Millin contain other such letters from Welensky to her.

The correspondence with individuals and institutions represents the continuation from 1964 of the 'Personal Correspondence' at MSS. Welensky Papers 584/2-686/11 above. There is a slight overlap at Dec 1963/Jan 1964 arising from the way in which the correspondence files had previously been divided. Individuals are named and arranged under their designations as at 1981; unchanged addresses are not repeated in consecutive entries. Running files of letters exchanged with occasional correspondents follow at MSS. Welensky Papers 785/1-790/4. Subjects remain diverse: new are sanctions and sanctions breaking (on the petty, domestic scale) and the passport problems of others (in which Welensky acted as an intermediary with the officials of the Foreign and Commonwealth Office). The correspondence with Dean Acheson is a photocopy provided by Professor J.R.T. Wood made when he was working on the archive writing The Welensky Papers.
