Daily Wireless and ElectronicsThe Compagnie Générale de Télégraphie sans Fil (General Company for Wireless Telegraphy) was created in 1918 and became known as CSF later on. They were heavily implicated in the development of communications and had their paws in the cable business, components, tubes, telephones, radios, military communications, broadcasting and whatnot, and they were also busy outside France, building emitters in Serbia, Poland (iirc) and such.
Something with nationalization, mergers, spin-offs, yadayada complicated financial organization, I mean just look at the companies listed!
Is the 1950s CSF the same as the 1920s one? Not really, but anyway have a March 1957 ad alongside the Nov. 1925 one ❤️

These resistors were manufactured in 1964, 61 years later they have driften some - as carbon composition types are prone to do.
Those were 43R when they put them into the box on 2 Nov. 1964, today they measure > 56 Ohms. A "little" bit beyond the 5% tolerance 👀

Whoops, slipped on a banana peel and slid right through to July 1900 which had this "Ever Ready" flashlight sold by the Paris dependency of the AENMC - five years before they renamed The American Ever Ready Company.
Interesting story this, how the British dependency became independent and then bought the American former parent.
Reminder that the AA dry cell was introduced in 1907 and the AAA in 1911 - they are by far less modern that one would generally think, thinken't they.
