1960's West German TN ( Tele Norma ) railway station flip clocks. We picked these clocks up recently from a small town just outside Berlin & they were used in the train station there. These clocks are plug in & have a pulse driver fitted so they're still running on their original mechanisms. Clocks come with 2 metres of cable & adapter which powers the pulse driver. Height 15cm, Width 31cm, Depth 14cm. This piece has an attribution mark, I am sure that it is completely authentic and take full responsibility for any authenticity issues arising from misattribution
