The 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 ❤️
