The archive of George Daniels documents his major contribution to horology and include his working papers and drawings, research notes and images for his published books, correspondence photographs and audio-visual material. The records are invaluable to researchers interested in Daniels' own work but also in historical watch and clock makers and tracing of watches, chronometers and clocks.

The earliest document is a volume of Daniels' lecture notes (LMA/4636/A/01/01/001) taken whilst studying at Evening courses at Northampton Polytechnic, St John Street, Islington in 1951-1952 (now City University London). In addition the archive contains: correspondence files, horological exhibition catalogues and papers (series reference LMA/4636/A/04); manuscript and printed technical drawings, calculations and sketches showing the development of the co-axial escapement with Omega and ETA of Switzerland with related patents (series references LMA/4636/A/03 and 04); photographs of Daniels' own watches (series reference LMA/4636/A/05); and Daniels' ledgers containing notes, diagrams and costings on his restoration work, historical watches and his own watches (series reference LMA/4636/A/08).

There are also Daniels' author files with draft manuscripts and research notes for his published books on watch and clockmaking, with photographs of watches used as images and copy business records of Breguet of Paris, France (series reference LMA/4636/B/01); photographs of historical watches and clocks (series references LMA/4636/B/03 and 04), events and studio portraits of Daniels (LMA/4636/D/03); his papers, photographs and video relating to Worshipful Company of Clockmakers (series reference LMA/4636/C); certificates awarded to Daniels (series reference LMA/4636/D/01); collected articles on his life's works and achievements series reference LMA/4636/D/02).

There are also films and video cassettes (series references LMA/4636/D/04 and 05) including talks given by Daniels with his feature in 'Aquarius' produced by London Weekend Television (1976). The archive also includes records of George Daniels Educational Trust (LMA/4636/E), namely Chairman's files on sales and bequests of Daniels' horological collection.

Radar Calculation by Maurice Henry Lecorney Pryce. Introduction to the calculation states 'The problem is to find the electromagnetic field due to a source of elctromagnetic oscillations placed near to a very large sphere. By large is meant that the ratio of the wavelength to its radius, and also the ratio of the distance of the source from the surface of the sphere to its radius, are very small. The source is supposed to be in vacuo. The material of the sphere is such that waves are attenuated in a distance small compared with the radius."
