  • No name or model designation is found on the radio. The only text is on the the backside: a) a sign saying 127 V vekselstrøm (127 V alternating current) b) a "stamp" with text "Patentafgift - Modtager 59357" (patent fee - receiver 59357) c) Jord (earth) on the left bushing. In addition the other bushings are numbered 1, 2, 3 from left to right.

    The radio is a 3 tube regenerative receiver with loudspeaker. It is probably made in Denmark.

    The loudspeaker drive assembly is much like an old headset receiver. An armature is carried by a spring. The distance between the armature and the poles of the electromagnet driven by the output tube is adjustable by a knob on the backside of the cabinet. The cone is connected to the armature by a thin rod. The rim of the cone is free and not glued to a support frame. The loudspeaker is oval 30 x 20 cm.
