Schuco Curvo 1000
The Curvo 1000 was made between 1950-55 by Schuco in Nurnberg.
It has got a Clockwork that can be set in seven diffrent patterns and it is the most advanced that I know of.
The patterns is set buy the screw on top of the steering rod and you can see what pattern it makes in the small window, just behind the front Wheel.
There has been replicas made after 2001 but only in red, and you can clearly see this on the bottomplate were replica is written.
The patterns that can be used, is on the backside of the box.
Replica box is availible for sale, just send me a mail.
