  The audio was originally recorded on Cyprus by the Cyprus Broadcasting Corporation (CyBC) sometime in the mid-to-late 1960s for their "Greek by Radio" series of lessons. The best guess is around 1967, the copyright date of the associated 3-volume "Learn Greek" textbooks consisting of the exact text of the lessons.
