This external radio speaker is a rare piece of technology from an era when speakers—once essential accessories for radio receivers—were a common fixture in households of the 1920s.

Its shape resembles a parabolic reflector or antenna, allowing for effective sound direction. The surface, with its copper-like appearance, lends an air of elegance. Standing on a sturdy metal base, it comes equipped with a cable and plug, hinting at its electric power source.

Yet, despite all efforts, the identity of its manufacturer and the exact model remain mysteries, lost even in the deepest corners of the internet.
