It's in a very good condition and are working very well. The Socius Motorbike was only produced for a very short period from 1938 until the beginning of the Second World War. The model has a clockwork motor for travelling forwards, which is wound up via a square bolt on the underside of the model. Its functions are special. When driving, a clapper inside the model produces a loud driving noise and the motorbike drives in serpentine lines by constantly steering the front wheel to the right and left. It has a bit of a preference for one of the sides. As a special feature, the passenger on the pillion turns past the rider in the direction of the bend in order to achieve a clear view in the direction of travel and better stability. The model was not re-issued after the end of the war. Marked with: Kellermanns trademark and patent for U.S and England underneath. See photos for the toys general condition.
