This model is virtually an upgraded type S51A with vibrator incorporated. The price of 2100 BFr is that of S51A (1850 BFr) plus vibrator (250 BFr). The original folder specifies DC mains supply for type U, while the configuration is suitable for operation on AC/DC mains. Until now, no S51U radio has been found. It is possible that the model type is S51AU as written in the Siera memento. |
