The Sport and General Press Agency is known to have been operating from 1910 until c1970 as a news and photographic agency. The company was based in Essex Street initially, before moving to Fleet Street. Much of the company's photographic archive was destroyed in a bombing raid in 1941.

Photograph with a caption that reads: '144902. "Kepes" Ephimeter. For measuring Young's Modulus and the modulus of internal friction. The purpose of this apparatus is to enable the modulus of elasticity and the coefficient of internal friction to be measured simultaneously. The test-piece is a circular cylinder. Its base being fixed in a rotating vertical shaft, it is acted upon at its upper end by a horizontal forces, the direction of which is fixed. As a result of the consequent rotary flexion every part of the test-piece is subjected to a sinusoidal tension and compression the frequency of which is equal to the number of revolutions per second performed by the rotating shaft. (Etaakissements Saintgobain).'

Photograph with a caption that reads: '144905. The Atomic Energy Commissariat of the French Republic. Electrode Forming Lathe. The following set up has been advised by Scribner (1) for all spectrographic analysis. A graphite cylinder is supported by a graphite rod, half the diameter of it. The assembly is arranged through a truncated cone joint. A piece is hollowed out at the top, so as to form a tiny crucible in which the sample is placed. The instrument is used for clean and quick forming of piece. The operation needs only 40 seconds the electrode is never touched by hand, keeping its original cellophane wrapper'.
